What is a water level indicator on a coffee machine?
Water level probes are a simple yet important part of every espresso machine. This probe allows the autofill boards to know when the boiler needs to be filled in order to protect the element from burning out and keep the boiler at the optimum level.
How much water pressure does a coffee machine need?
For the most part, 7-9 bars of pressure is considered the sweet spot for pump driven espresso machines, which use a pump to force water through the grounds. Pump driven machines, as well as rotary ones, are known to be much better than those that brew using steam, known as steam driven.
Why is my coffee machine not pumping water?
There are two main reasons there’s no flow coming from your group: a clog or a faulty brew valve. Make sure all of the valves are turned on. Most espresso machines use solenoid valves to control the water flowing through the brew head. Engaging the group head causes these valves to open.
How do you clean a water probe?
Clean the sensor pins gently with a toothbrush. A small amount of Degritter’s cleaning fluid can be added to the brushes. Once the pins are cleaned, brush them once more with a toothbrush rinsed in clean water.
How do water probes work?
Water level indicators work by using sensor probes to indicate water levels in a storage tank. These probes send information back to the control panel to trigger an alarm or indicator. As mentioned above, the control panel can be programmed to automatically turn on your pump to refill the water again.
How many bars should a coffee machine have?
9 BARs
One of the best BAR pressures for a coffee machines is 9 BARs. Some claim that 7-8 BARs is even better. Why? Anywhere between 7 to 9 BARs is optimal for a perfect espresso extraction, leading to rich, tasty, balanced and creamy beverage.
How do I increase the pressure in my coffee maker?
To fix this you may need to one or more of the following:
- Change the grinder to a finer setting.
- Increase the Dosage (amount of coffee)
- Apply more pressure when tamping.

How does ice thickness sensor work?
The ice thickness probe provides input to the control board. The ice thickness probe sends two signals: 1. Water is not contacting the probe. When water contacts the ice thickness probe for 7 continuous seconds and the six minute freeze cycle lock-in has passed, the control board will initiate a harvest cycle.
