How to Clean Screens on a Hotpoint Dishwasher HDA2220

If your dishes don’t come out clean when using a Hotpoint dishwasher HDA2220, and you’ve checked the hardware of the appliance, check the water level. Start the machine through a dishwashing cycle, wait until it’s filled for a second time and open the door, which will automatically stop the cycle. Check the level of the water inside the machine. The water should have reached the level of the heating element. If it hasn’t, your intake valve screen is most likely the problem. Intake valve screens on the Hotpoint HDA2220 can become clogged with dirt and other particles, and this can interfere with the incoming water flow.
