As 80% of the reported issues are mainly due to lack of understanding of how the machine works or user errors.
We had pieced some commonly reported problems here which will help.
Issue: What sort of water should I use?
Solution: Clean, soft water. Not mineral or alkaline water.
If you are located in a location with only hard water available, it has to go through a water softener and water filter if necessary.
Minerals from hard water can cause damages to the machine in the long run and needs to be descaled according to the water hardness rating.
Minor descaling can be done by using the descaling agent. (Warning: Do not activate the pump for more than 60 seconds without half time of rest)
Severe descaling should be done by professionals.
Issue: Should I do regular descaling?
Solution: That depends on the hardness level, though preventive descaling is recommended, instructions can be found here: Puly Caff Descaler.
We will suggest working on keeping your water soft than worry on descaling. As descaling can be a major and expensive task for severe cases.
Descaling can also damage components during the process.
Issue: My machine can’t start working on the first use. (On water tank)
Solution: Check if your water tank is full. If it’s not, the machine won’t start pumping as a precautionary feature.
Issue: Set to plumb in mode.
Solution: Please refer to the instruction manual for the specific details.
First of all, do not switch the machine on until your machine had been correctly configured to connect to the water networks.
Please refer to the machine’s user instruction manual for more information.
For Bezzera machines with TOP(Mitica/Strega), the machine comes in Tank mode, with only B connected.
For Plumb in mode:
i) Connect A to the metal end, which bypasses the water tank’s low water sensor.
ii) Screw the plug provided into the water inlet under the water tank.
Reverse the steps to restore back to Tank mode.
Second, check if your water network has sufficient water pressure. In some places, water comes out at dropping amount. Water is best at 2-4 bars pressure.
Pressure too high will lead to overpressure in brewing.
Issue: Water is not coming out.
Solution: Check if your water network is properly connected or water tank is full.
If your machine is on water network mode.
The inlet pressure should force the water through the system. Check if the settings are right according to the manual.
1. Switch off machine.
2. Check water tank is full.
3. Take out the loaded water tank and put it back again to ensure it fits properly.
4. If the machine draws water by a water hose, check is the hose submerged under water inside the reservoir. The inlet hose is usually the longer tube.
[For Expobar]If the water filter isn’t attached and used, which also act as a weight. Check is the hose floating up to the surface of the water.
5. Switch on the machine and the pump should start pumping. Allow it to pump for 10 seconds and switch off, check is the water drawing in from the tank. Do it for not more than five times.
6. DO NOT allow the pump to pump continuously for too long. For every two minutes of work with the vibration pump, it requires one minute of rest.
7. If water is drawn successfully from step 5, the machine should be ready to activate fully by itself.
If it doesn’t work and you can hear that the pump is working, there might be too much pressurised air in the system, and it requires a remedy by forcing water through the tube manually.
Issue: My machine suddenly stopped working on the first use after switching on. (On water tank)
Solution: This is common particularly with double boilers. Your water tank had run out of the water after drawing all its water to the boiler for the first time. Refill water and it should start.
Issue: Water is dripping around the grouphead while it’s brewing.
Solution: The grouphead gasket maybe dirty, with coffee grounds and is unable to seal properly with the portafilter.
It can also be due to the portafilter not tightened enough.
Lastly, it’s possible that the grouphead gasket had worn and torn.
Issue: How to replace the shower screen or grouphead gasket?
Solution: For BZ series, please refer to the product page here: BZ13
For E61 and spring pistons, refer to the following video:
Issue: Why is my brew pressure showing pressure when it’s idling?
Solution: It’s normal. As the boiler is full, when there’s fresh water add in or when the machine heats up for various reasons. It will lead to expansion, and it shows an idling pressure.
The idling pressure isn’t important unless it’s going very high above 12 bars.
Issue: Why is my brew pressure no longer as much as before.
Solution: Check your grinder setting and your coffee condition. The condition of your beans or grinder may have changed leading to flowing faster. Hence, holding lesser brew pressure.
Issue: There’s a frequent flickering sound, water indicator is off, idling heat is unstable.
Solution: The machine is unable to detect water. Your water is too soft. Pour the current tank of water away and replace with another tank to try. Please make sure that the water tank is correctly positioned.
Issue: I think my brew pressure isn’t right.
Solution: Check with a blind filter. It should show the maximum amount of pressure.
During an actual extraction, it will show lesser. It’s simply due to the flow of water passing.
Readings from not using a blind filter are not significant.
ALWAYS test brew pressure with a blind filter.
Issue: Button is feeling sticky or needs to press a couple of times to activate.
Solution: Dust, humidity and dirt had congregated in the button.
The environment is most likely to be too dusty.
For an easy DIY fix, remove casing and locate affected buttons.
Spray contact cleaners at button’s contact.
Please switch off the machine, remove the plug from the power supply before performing any fix.
Issue: My E61 handle on the brew controller seems loose.
Solution: There’s a screw beside, use a minus screw and tighten it.
Issue: The white film on my espresso machine is coming off / The sticker on the Expobar Control’s electronic control is coming off.
Solution: The sticker/film does not serve any purpose except protecting against scratches; it can be taken off.
Issue: The portafilter silicon gasket in my machine came out.
Solution: Normally new users may report this, and it can happen easily if the user releases the portafilter when the brew chamber is still pressurised. Especially in models like Bezzera Strega or B2013AL which has no release valve.
Please refer to the following video on how to put it back. At the same time remember to give the group head internal a good brush and wipe if you haven’t been doing.
Issue: My steam or water wand is very loose.
Solution: This is normal for a new machine. The fresh coat of lubricant is doing its job. It will season over time.
Issue: My steam or water wand is very tight.
Solution: Purchase some lubricant from our store and apply it around the ball joint.
Issue: Steam is not coming out from the steam wand
Solution: First check if your water wand is operating properly, water is flowing on activation.
If it does, it means that your steam wand is stuck.
The most likely reason is milk was not properly purged after use, milk solidified and choked the steam wand.
It is more liable to happen to a single tip steam wand.
1. Switch off the machine and allow to cool.
2. Remove steam wand’s tip.
3. Check and remove any blockages.
4. Turn on the machine and allow to heat up.
5. Purge steam wand without the tip installed.
6. Reattach back tip.
Issue: Water is dripping from the tip of my steam wand.
Solution: This is most likely residual water stuck in the steam wand during the last use.
Issue: My steam wand is leaking.
Solution: Turn the steam wand and check is the securing nut loose and moving. If it is moving, tighten it.
Do not over-tighten! Tighten by 2cm each time until the wand can turn without moving the nut.
Lubricate the ball joint at the steam wand to reduce the friction which reduces the chance of the nut loosening again.
Issue: Water is dripping from the spigot behind the brew group during heat up.
Solution: This normally occurs during starting up, it’s residual water coming off from the last use. Together with water released from expansion during heat up.
Issue: My portafilter is turning colour, there’s something wrong with it.
Solution: Soak the metallic parts in a water mixture of grouphead detergent. It will restore the condition by stripping the oil.
Avoid having the detergent in contact with the portafilter handles.
Issue: Water is leaking from the grouphead.
Solution: Most likely your grouphead is dirty. You can use the provided grouphead brush to flush it.
Coffee may also have built up and prevent a complete seal. Please be reminded that the shower screen with the grouphead gasket should be taken down to clean periodically.
Preferably at least once every half a year. You should also do grouphead flushing with water after your last cup of the day, and with grouphead detergent at least once every two weeks.
Frequency will depend on among of usage.
Please refer to the following video on how to remove and put it back. At the same time remember to give the group head internal a good brush and wipe if you haven’t been doing.
You can purchase additional gaskets and shower screen from us.
Issue: There are steam and a little water, suddenly the machine isn’t working.
Solution: Water had run out. Check your water supplies are sufficient, or they are correctly fit.
Issue: The machine is getting noisier.
Solution: Normally there’s nothing wrong with the machine. The pumps are on holding stands that reduce vibrations. Your area may be too enclosed, and the echo amplifies the noise. Drip tray can cause rattling sound if they are not properly placed. Likewise for cups that may knock to each other or the top trays.
Issue: There’s a pool of water under the machine.
Solution: Normally it’s from overflooded drip trays. Clear them regularly.
Or it could be your water tap not closed tightly.(Expobar)
Issue: There’s a pool of water under the water or steam wand(Expobar).
Solution: The valve wasn’t closed tight enough.
Issue: My machine is too hot.
Solution: Flush a little before brewing. Especially if it’s been idling for some time.
Issue: My machine isn’t hot enough, or the steam is too weak.
Solution: Make sure the machine had heat long enough.
If it is unable to heat adequately, scales may have form and descaling will be necessary.
Issue: How should I clean the machine?
Solution: Please follow the user manual instructions or email us on the model you purchased for more information.
Issue: Nothing is coming out from my grinder.
Solution: First listen to the motor if it’s working. If it’s working, there shouldn’t be any technical issue.
Grind setting too fine
The burrs are too close together to allow any beans to pass.
Release the grind setting to be much coarser.
As coffee is naturally oily and sticky, particularly dark roast or coffee from certain origins.
They may stick to the wall of the nozzle. Over time, it can potentially accumulate, harden and obstruct the vent from dispensing coffee.
Another possible reason is massive grind settings had been made, and beans are stuck between the sides of the burr, jamming the grinder.
To solve it:
1. Unplug and ensure that the grinder is off.
2. Empty and remove bean hopper (Unscrew if necessary)
3. Vacuum the remaining beans out from the inlet.
4. Turn to a very coarse grind.
5. Plug and switch grinder back on.
6. Grind for a short duration and see coffee is out.
7. Slowly make your grind finer and press the grind button if you think beans may still be in there.
8. Go on making your grind finer until it reaches your estimated grind level.
9. Replace hopper and refill with you coffee beans.
10. Adjust the grind and cup to make sure your coffee is tasting perfect.
If it doesn’t work, it could be jammed at the outlet with too much accumulated coffee.
Use the grinder brush and clean it. (Off the grinder while you do it)
To prevent this from happening.
It is recommended:
1. to use the grinder cleaner or clean the grinder regularly.
2. clean the outlet with a grinder’s brush regularly.
3. do not make big grind adjustments unnecessarily.
WARNING: NEVER PUT YOUR FINGER INTO THE GRINDER WHILE IT IS ON.
Issue: I turned a few rounds on the Bezzera BB005 Grinder and things don’t change much.
Solution: It is a stepless grinder, turning one big round only moves a little.
Refer to the grinder’s product page for more information. Bezzera BB005 Grinder
Issue: The extraction isn’t ideal. I think there’s a problem with the pressure.
Solution: All espresso machines are tested to work at its best performance before leaving the factory.
As different manufacturers have a different way to how water travel within the machine, it is not advisable to take the settings of other brands as the assumed preferred configuration.
Pressure adjustment should be the last resort.
Issue: The extraction isn’t ideal, what should I do?
Solution: Most common reason for a bad extraction is coming from the grinder. The grind setting isn’t right. Either a problem with the particle size, the dose amount or both. That does not suggest that a bigger or more expensive grinder does the job better. It’s the amount of coffee, or its grind size is not able to hold up the water appropriate enough to allow coffee to pass at the right speed.
Issue: My extraction is coming out too fast; the crema is very thin
Solution: If coffee isn’t the issue, it’s usually a problem with the grind setting.
Increase the fineness from your grinder’s setting.
Your coffee, maybe not fresh enough.
Increase your tamping pressure.
Increase the amount of powder.
Different origin of coffee has a different level of oiliness that directly affects the amount of crema. Some coffee is naturally less oily.
Issue: My extraction is coming out too slow
Solution: If coffee isn’t the issue, it’s usually a problem with the grind setting.
The first remedy – tamp lighter.
Decrease the amount of coffee powder.
Increase the coarseness from your grinder’s setting.
Issue: My extraction is still bad, my grinder isn’t the problem. What should I do?
Solution: Your coffee may be not fresh enough. Or the coffee that you have has lesser oil, either due to the nature of the bean, a bad grade, or inadequate processing.
Pure Arabica blends are typically more challenging to extract. Coffee with a little mix of Robusta has a richer amount of stabilised crema.
Issue: My coffee is very sour.
Solution. It’s normally due to the nature of the beans, or the roasting is too light. Try with a darker roast and with coffee grown closer to the equator band.
If your machine has a PID, you can try to tune the temperature higher.
If it’s a heat exchanger, you can flush lesser.
Issue: My coffee is very bitter.
Solution: Pick a lighter roast blend or with a lesser composition of Robusta beans.
If your machine has a PID, you can try to tune the temperature lower.
If it’s a heat exchanger, you can flush more.
Issue: I want to find out my brew pressure.
Solution: Check with a blind filter. It should show the maximum amount of pressure. Actual extraction should reduce a little.
