Jay for Model Number SHEM78W55N/01 I have 2 issues with my dishwasher I often get error code E24 and also the program times don't run as scheduled. I have checked that the pump runs and the drain is not clogged, used the reset function and haven even cleaned the line with air pressure but still hit or miss as to complete draining or not. The programs have also been erratic, as the timer counts down, it will usually jump back up; going from say 16 minutes or so remaining back up to 45 for example. When this happens it is also hit or miss as to whether or not the cycle will finish or have the E24 code. The drainage pump does run and someone suggested it's probably a computer problem but if so is it the power module or operating module or something else. Thanks
Answer Jay, as there are no obstructions, the drain pump 00631200 will need to be tested for resistance. From terminal 1 to 2, 1 to 3, and 2 to 3 there should be a resistance reading of 130 Ohms. If the resistance is good, the most likely cause of failure would be the power module 12016881. Read More... Answered by AppliancePartsPros.com | Thursday, January 12, 2023
