Cooper S Hi, I have a Thermador DWHD770WPR giving an error code E18. It started giving this after we swapped out our leaking hot water tank for a new one. I've checked the inlet hose for kinks, unplugged the dishwasher for hours, run the faucet, and have confirmed that hot water is reaching the dishwasher by manually opening the inlet valve with 120VAC. When I turn on the unit, it immediately errors E18. Could the valve be the issue? Any suggestions? Thanks.
Answer Cooper S, Thermador's error code E18 - Means: The water level is too low, or water is not being pumped correctly. 1. Check the inlet hose and make sure it isn't kinked or damaged. 2. Make sure the water supply is turned on. The water flow rate is too low. Read More... Answered by AppliancePartsPros.com | Friday, August 23, 2024
