Dishwasher only drains in specific circumstances

"@mrdishwasher

According to the program chart for your DW it is supposed to drain at the beginning of every program. After that it changes a bit. So it seems like it starts off doing what it is supposed to do but does not follow through. The plastic “tank” in your picture seems to be the air guide assembly and it looks like the “check valve” is doing its job as well. Of course you can always check the flow sensor in the air guide assembly which monitors the flow of water entering the DW and acts as a float switch. Most likely it will not be the case in your no drain situation. I wonder if this is an issue with the control board of the unit.  You could always rig your meter with a bunch of long wires and connect those to the drain pump. See if you get a signal to the pump during the cycle when it is supposed to drain."

Dishwashers, like other automatic appliances, are equipped with various sensors. Their work is aimed at controlling water, temperature, and the number of revolutions. All these readings allow the electronic board to regulate the operation of the machine. The dishwasher pressostat is another sensor. It controls the water level in the tank, and therefore is an integral part for the normal operation of the equipment. I ran into a terrible problem, my dishwasher failed. I absolutely did not know how to fix it and my friend advised me to contact https://www.wilcoplumbing.com.au/plumber... plumber lane cove and they helped me.
