PSSR stands for Pressure Systems Regulations (PSSR 2000). It is a statutory examination that must be carried out every 12 months to cover safe use of pressure systems, such as your espresso machine. It is essentially a boiler check, without it, you may invalidate your warranty and insurance, but most importantly, your machine may not be safe and could harm yourself and others around you.

Our in-house engineers have been trained and are CoffeeSafe registered so that they can carry out the testing with ease. After completion of the test, you will receive a comprehensive engineer report, and a written scheme of examination and PSSR certificate.

Explain it further!

To break it down, it’s all about pressure. Pressure is used in coffee machines to force water through coffee pucks to create your cup of coffee. If you have seen or used an AeroPress, this is a similar concept, you have to force the water down to filter through the coffee.

In an espresso machine, there is a pressure relief valve that keeps this at a safe level. If the pressure looks like it’s creeping too high, the valve will open to release some pressure. However, if it malfunctions it means that the pressure inside has nowhere to go, which eventually will cause your machine to explode. Machines explode in lots of different ways. Sometimes the roof will blow off and up, sometimes the walls bloat out, or fly off. Sometimes the whole machine will jump in the air, like you can see in the video below. Either way, it is best to avoid this situation, which is why a PSSR test is so important. Get in touch with us to book yours in.

A PSSR examination will include

• Our engineer will strip down the espresso machine.
• Drain out the boiler and remove heating element.
• Our engineer will then proceed to inspect the boiler inside out including the safety valve.
• Our engineer will then reassemble the coffee machine and change the heating element gasket.
• The machine will then be tested at full pressure (1.7-.1.9 Bar) to see if the safety valve function correctly and opens at the designated pressure it is been built for (usually 1.8 Bar).
• After all of that is been done, we will issue a PSSR Test Certificate for the coffee machine to indicate it has passed.
• On the rare occasion it fails and cannot be repaired within the allotted testing period, (spare part required and not available) then a second inspection visit will have to be arranged and your machine cannot be used until it has been passed. However, we can maybe look at alternatives to get you moving until then.
