Pam for Model Number SHU5316UC/U12 My Bosch dishwasher showed 2H when I started it; it usually shows 74 and counts down. It ran for longer than the usual time frame. The timer went down to 1 and never shut off; seems to have been rinsing forever! Is it the control module that has gone haywire? Thank you.
Answer Hi Pam. This means the control module has timed out due to an unidentified heating problem.All heating related parts must be checked until the problem is found. If the dishwasher has not stopped washing the module is OK. If the dishwasher has stopped then it is timed -out. The N.T.C. sensor reads 55k ohms @72 degrees. The heater reads 11 ohms. the control module heater relay is working? The circulation pump reads 10 ohms. The flow switch reads .4 ohms. The high limit reads .3 ohms. The wiring harness is OK? You may however prove to get an authorized service technician to completely check all components. Thank you. Read More... Answered by AppliancePartsPros.com | Monday, July 18, 2011
