If you are not getting water out of the grouphead of your A53 Mini, following along with these troubleshooting steps may help you find the cause of the issue.
The water tank isn’t full: If the low water light is illuminated it means there is not a sufficient amount of water in the reservoir, or the water tank isn't being sensed by the water tank sensor. Refill the tank, ensure the white magnet float in the rear corner is not stuck at the bottom and the machine should be operational again. If the low water light does not go away after refilling the tank, look into the next step. If the low water light is not on move past the next step onto the following steps.
The water tank sensor needs to be moved forward: Occasionally, the water tank sensor will get pushed back a bit too far and will need to be moved forward. This is simple to do, all you'll need to do is remove the water tank, reach into the machine and pull the water tank sensor forward a bit. Before doing this, unplug the machine just to negate any possible safety hazards.
The grouphead solenoid doesn't click open: When you press the one or two cup button there should be an audible "click" of the grouphead solenoid opening. If you do not hear this click, you may need to either clean the solenoid or replace it. If cleaning it does not work, contact us at firstname.lastname@example.org for further assistance.
No Flow From Pump: If you hear a rattling sound coming from the machine, the pump may not be getting proper flow through it. You can verify flow through the pump by removing the panels, removing the fitting shown here and turning the pump on with it aimed into a cup. If you are not getting any flow and the pump is rattling, you may need a new pump.
If your machine is displaying the error code for the flowmeter alarm, which is the first 3 digits on the control panel when pressing the 1 cup button, or the 4-6th digits when pressing the 2 cup button, you can follow along with these next steps to determine where the blockage is occurring.
Blockage In Flowmeter: You may have a blockage in the flowmeter itself. You can check the inside of the flowmeter by following along this article: A53 Mini Flowmeter Cleaning
Blockage At 3-Way Valve: If your pump turns on and you get pressure showing on the gauge, you may have a blockage at the 3 way valve of the grouphead. You can follow along with this article for instructions on how to clean it: A53 Mini Grouphead Solenoid Cleaning
