How to Troubleshoot a Hotpoint Dishwasher

If your Hotpoint dishwasher is not working properly, you may be able to troubleshoot it yourself and avoid expensive repair fees. Many common problems are caused by a simple part or two that can quickly be replaced.

Replacement parts are available at most home-improvement stores, or you can order them directly from Hotpoint.

Look at the troubleshooting section in your dishwasher's instruction manual. Hotpoint manuals list many common problems, and you may be able to identify the problem without taking the dishwasher apart. If you do not have your instruction manual, write down the dishwasher's model number and check the Hotpoint website for a downloadable copy (see Resources). The model number is usually found on the dishwasher's frame, or right under the control panel.

Test the Hotpoint dishwasher with a multimeter if it is not filling with water. This often means the fill valve is broken. Take off the access panel from the front of the dishwasher so you can reach the fill valve attached to the copper bracket. Touch the multimeter's probes to the two black terminals at the top of the fill valve. If it reads 120 V, replace the fill valve. Check the screen between the bracket and fill valve to make sure it is not blocked by debris.

Look for leaks around the lower spray arm or soap door. Check the plastic on the lower spray arm to make sure it is not cracking down the middle. Replace the arm if you find any cracks or splits. If the soap door is leaking, it probably needs a replacement gasket.

Inspect the door latch if your Hotpoint dishwasher will not start, or is stopping in the middle of a wash cycle. This can be a sign that the latch is failing and the dishwasher does not recognise that the door is closed.

Test the water temperature if the dishes are not coming out clean at the end of the wash cycle. The water in the dishwasher should be 48.9 degrees C so that it can remove tough food stains and grease. If you are not getting hot water to the dishwasher, call a plumber to inspect your home's water heater, or check for clogged pipes.
