What F-3 means

F-3 on Dacor EDW and IDW 24-inch dishwashers from the older WPS platform is listed as an electrical problem, and it comes up when the water temperature does not rise as it should during the cycle. The heating circuit is the suspect. The dishwasher shows F-3, and dishes may come out cool, wet or not fully clean. If your machine is a few years past warranty or much older, that is fine with us. We repair it and tell you plainly if the repair would not pay off.

Common causes of F-3

Heating element not heating
Temperature sensor misreading
Wiring or connector at the heater
The control board

✓ One safe check you can try

1. Run the kitchen hot water until it is hot, then restart the dishwasher so it starts with hot water. 2. If F-3 returns, stop using the dishwasher and schedule service. 3. Do not open any panels yourself, since the heater is a live electrical part.

! Why to stop there

Whether the element heats and the water temperature rises
Whether the sensor or the control is giving the wrong reading
Which parts are available for the older platform, confirmed first

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F-3F-3 questions

What does F-3 mean?

The dishwasher did not see the water get warmer as expected, which points to the heating circuit. The control stops the cycle to avoid running with no heat.

Will hot tap water fix F-3?

Starting with hot water helps the cycle, but it will not repair a heater that is not working. If F-3 returns, the heating circuit needs a test.

Do you replace heating elements in older Dacor dishwashers?

Yes, when the part can be found. We confirm availability before the repair, give a written price first, and the work has a 30-day workmanship warranty.
