What’s covered in the grouphead maintenance service?

Grouphead maintenance will cover the front part of the machine, on the grouphead and the wands where there are exposed to the most wear and tear.

1. Replacement of grouphead gasket
The gasket that takes the most damage from wear and tear. Serve to secure a seal between the machine and the portafilter.

2. Replacement of shower screen
Water disperses from the shower screen to the coffee. If grouphead flushing wasn’t done diligently, rancid oil from the remnants may pass on to the next cup and cause an uneven distribution of water.

3. Cleaning grouphead sprayer. (If available)
Only applicable for the BZ grouphead. The part where water gets distributed evenly to the coffee bed.

4. Replacement of steam wand seals
Over time, the steam wand may become stiff and the friction cause damage to the gaskets, resulting in water leakage.

5. Lubricating of steam and water wand
All lubrication will be done with a higher grade lubricant, used by the factory from Bezzera. If the lubricant wears off, it makes the wand stiff in moving and can loosen the entire steam wand from the machine.

6. Replacement of cams, gears and gaskets in the grouphead
This is the internal of the grouphead that may get worn off from usage. These are mostly associated to the E61 grouphead. The main reason why they cost a lot more in parts and labor. They normally take 3x longer to service.

7. Basic inspection
A visual check on some of the commonly worn parts and advice on replacement if necessary. Do note that we are unable to predict the longevity or status of every component and inspect the interior of the boiler and tubes.

Grouphead maintenance service does not include any repairs or maintenance in the main body of the machine where the boiler and most components are located. Polishing is not included but we will perform some basic cleaning inside the grouphead. During maintenance, we may inspect and provide advice on parts replacement. We are unable to examine the interior of the tubing and boiler.

The following are NOT included.

The following parts can be replaced upon request or under our recommendation when we do a check. Price will vary depending on the model.
We will provide a 25% discount to the replacement of the components if it’s done together with grouphead servicing.

Do note that our technicians can’t visually see through the machine to observe the condition, as such assessment can’t be 100% accurate. We will still recommend replacing certain components even if they are deemed working. Normally replacements are required more often if:

• The machine was used with untreated water that had never been softened. Worse, if the user was using mineral water.
• The machine was switched on 24/7, all the time.
• Users who backflush for long durations and the machine is using a vibration pump.
• The premise’s power supply is prone to surge.

The most common reason for machines to fail is from limescale build-up. You can refer to this article: Water softening

Here are some of the tune-up jobs you can request.

Replacement of power relay (Recommended)
If your machine has a tic-tac sound while it’s on standby, it’s coming from this switch. This component does a lot of work whenever the machine is on.
Models that will need to replace this part more frequently are machines without PID digital temperature control.

Replacement of Pressurestat
Most of our machines sold are with a pressurestat. If your machine does not have PID digital temperature control, which has a display. Also, if you hear a tic-tac sound every 1-2 minutes after the machine fully heat up, your machine is using a pressurestat.

Replacement of vacuum relief valve 
This part is located on top of the boiler, it bleeds out air from the boiler when the machine cools. It’s not connected to any electronics but they are one of the easiest parts to cause issues from limescale. Sometimes, the gasket in the valve may snap or be hindered by limescale, causing steam leakage.

Replacement of pump
For machines that use a vibration pump, the typical lifespan is around 5 to 7 years.
Vibration pumps can fail for various reasons, the most common reason is due to overloading. Vibration pumps used in the Bezzera has a duty cycle of 2:1. Meaning for every 2 minutes of work, it has to rest for 1 minute.
Sometimes users extract for too long or flush very extensively, which could damages to the pump.

If the machine is using a rotary pump, they are not limited by duty cycle but Rotary pumps may get damaged if they run dry without water passing or limescale formation.

Replacement of water level probes
These sensors on top of the boiler check the water level inside. Machines that do not use softened water may have limescale covering the sensors. This can lead to major damage to the heating element, pump and other issues. Given that they are not expensive, they are recommended to be changed if limescale was detected.

Replacement of overpressure valve 
The valve regulates the passing of water. 

Replacement of PID
Your machine has a PID if it has a digital controller for temperature.

The PID is made up of a few electrical components. They are the temperature probe, the display and the controlling module.
Normally the electronics fail from moisture, electricity and sometimes overheating. Overheating can occur if the user set the temperature excessively high or the machine lacks ventilation.

Replacement of solenoid
Solenoids are electromagnetic switches, connected to a valve to control the flow of water. Most machines have at least 1 solenoid. Limescale formed from minerals in the water may jam the solenoid. The switch which is an electronic, could also be damaged by moisture or electricity.

Replacement of heating element
Machines that do not use softened water may cause limescale to form around the heating element. Leading to heating and functionality issues. Limescale sticking on the heating element could also cause hot spots which burn out the component. This component can also be damaged by power surge, or from other defective components. We will usually replace this part with the power relay.

Replacement of level controller
The main coordinator for all the functions. Normally damaged by unstable power supplies, component failure or moisture.

Replacement of brew or boiler gauges
This allows you to read the status of your boiler and brew pressure. They are normally damaged from limescale buildup.

Capillary hoses to the brew/boiler gauges
These hoses are very narrow and are easily clogged by limescale.

Replacement of Safety Valve
One of the safety precautions for the espresso machine. Releases excess steam when the pressure exceeds safe values. The safety valve normally lasts for a long time. It’s totally mechanical and located at the top of the boiler.

 

Descaling

Descaling should be the last resort and it may not to clear all types of limescale with the usual food grade descalers. It’s not unusual for problems to arise or components to fail after descaling.

The cause of most major issues comes from using water that had not been softened adequately. This is the same for any types of coffee machines, except that semi-professional machines are designed to be serviceable. Users who diligently soften the water can expect their machines to last much longer before any repairs or maintenance required. To know more about water softening, please refer to the following page. Water softening

Also, it’s important to understand that the maintenance service should not be taken as a way to request a repair for any existing issues. A repair service will require more troubleshooting and investigation of the water circuitry and electrical network.

When should I do maintenance?

It’s impossible to accurately gauge when is maintenance required as it depends on the usage, cleaning habits from the user, and the water condition.

Commercial environment

Like your commercial ovens, dishwashers and filtration systems. You are recommended to do a servicing every 6 months to maintain your machine at its most optimal condition. During the maintenance, we will do a brief checkup on the internals which will increase the reliability and reduce your downtime during operation.

Office or showroom environment

If the machine is used heavily and is mission-critical. Or if you are aware that the machine was not maintained adequately. We will recommend that you send for servicing once every 6 months.

Otherwise, we will recommend sending in the machine at least once every 2 years.

Home environment

Home users can purchase the gaskets and service the group or wand gaskets on their own. For users who make less than 5 cups a days, we will recommend sending in the machine once every 3 to 5 years.

Overall, we recommend maintenance to be done once at least once every 3 years or after 3000 extractions, whichever first. It is possible that your machine can last for decades under proper care.

Like any coffee machines, users should do preventive measures like grouphead flushing for E61/BZ machines and use softened water for all types of espresso machines. Regular descaling should be done if a softener is not used. Mineral water should never be used as minerals will form solids that will clog the system. If you wish to use a direct water supply, please attach a water softener before connecting to the coffee machine. Do note that not all water filters soften, check with your vendor for more information on its softening capability.

How long will it take to finish the maintenance?

Depending on the severity or any additional jobs required, it typically takes 4 to 8 hours just to replace all the small components.
Food grade sealant, which is the type of glue applied to pipe connections to prevent leaks will take a full day to strengthen and cure. Followed by pressure, heat tests and other observations. Reapplication of the food-grade sealant may be required again.

The technician is also unable to work on pressurised and hot machines, thus periods of cooling time are required. As such, maintenance is impossible to be completed in a day and can’t be hastened.

A job well done will take at least 3 working days to fully complete.
Do note that maintenance is based on first come first serve, thus a further waiting time might be required.

We will recommend clients schedule maintenance before the peak seasons, especially Christmas and Chinese New Year.

Below are some photos of poorly maintained espresso machines used in Singapore

Please do not misunderstand that all professional or semi-professional machines are hard to be taken care of.
The issues above could be avoided if the user softens the water, perform grouphead flushing if necessary and purge the wands.
