Question about Bosch 24 in. SHU43 Built-in Dishwasher
HI,DISHWASHER CLEANS GREAT.BUTTAKES 3-HOURSTO GET THRU ALLCYCLES.
Bosch dishwashers are designed to heat the water to temp. However it has a 3 hr default if it doesn't reach temp. Start the cycle and see if after 1 hour if the water is hot or cold. If hot, then it is heating the water and the water coming in is just too cold. You may try running the water at the sink to get it hot there first before starting the dw. If the water is cold, then your unit isn't heating the water. At this point I pull the outer door panel, find the largest wires on the control unit and put my meter leads on them then start the machine. You will see 120 volts on your meter. Start the machine in light washes and with in 10 to 15 minutes you should see 0 voltage. Than means the relay has closed in the control and the hot line of the 120 volts is being sent to the heater. If this never happens, then you have a bad control. Bosch dishwashers have a 5 yr part warranty on the electronic control. Now If you get the 0 volts, I will put my amp meter on one of the same wires and check for 9 to 11amps. If that isn't there, then you have a bad heater assy. Hope this helps
