How To Avoid Common Coffee Machine Problems

As with most machines, no matter what brand or model you go for, eventually, you’re going to need a coffee machine service. A high-quality coffee machine is very robust and durable, but over time, without the right maintenance, your caffeine experience is inevitably going to degrade.

At Corporate Coffee Solutions, we provide our customers with the highest quality coffee machine hires and services. So, to help you ensure that you can still get that perfect espresso each and every time, let’s take a look at how to avoid the most common coffee machine problems.

Water Worries

You would be amazed how many coffee machine service visits could be avoided by simply using better water. Particularly in Adelaide and Perth, tap water can be quite “hard”, containing a large number of impurities. This, coupled with the pressure, heat and frequent use of your traditional espresso machine, can do tremendous damage to the internal workings over time.

For those that have smaller coffee machines, this can be avoided by using filtered, “soft” water in your machine. Not only will this help you to avoid issues down the line, it will also greatly improve the quality of your coffee. However, for those that have cafe-style machines that are hooked directly to your water system, different methods will be required…

Backflushing is Your Friend

Think about how often you drink things that have come out of your coffee machine. Hopefully, that mental image will hammer home the importance of cleaning the insides of your machine, as whatever may build up in those pipes is invariably going to have an effect on your coffee. That’s why backflushing is one of the most important factors of a coffee machine service, and why it’s vital that you know how to do it.

Here’s a quick rundown of what to do before you start:

  1. Clear as much coffee from around the group head gasket as you can using the brush that came with your machine, and run through the brewing cycle to rinse away the rest of the residue.
  2. Place your empty blind filter (the coffee filter without holes for liquid to pass through) in as if you were going to make a coffee.
  3. Turn on the brewing cycle for approximately ten seconds.
  4. Turn off the brewing cycle, wait, and then repeat the process two more times.
  5. Clean off your blind filter, add some coffee machine detergent to it, and then go through the process again.
  6. Repeat the previous step again and repeat until all the detergent foam is gone.
  7. Rinse and you’re done!

This process may seem long and complicated, but it’s really quite simple. Doing this on a semi-regular basis will save you from a lot of common issues, thereby saving you money, and ensuring an excellent, delicious espresso each and every time.

Living With Limescale

Have you ever made a cup of coffee and tasted a distinct change in flavour? Limescale is a reality for all coffee machine owners at one time or another, which is why descaling should be part of your standard monthly cleaning routine if possible. To work out the best method of descaling for your machine, it’s best to check your user’s manual, which should have specifics on how to keep your machine running optimally whilst avoiding potential damage.

Alternatively, descaling almost certainly be part of your coffee machine service. However, as with most maintenance tasks, it’s a good idea to learn how to do it for yourself as well, as this will lead to less professional cleaning being required.


Following these steps will help you to prevent the vast majority of issues, and help you to stave off a coffee machine service for the foreseeable future.
