The part that holds your dishwasher door shut is called a door latch. To determine if the thermal fuse is bad, remove the control panel, locate the fuse, and test it for continuity. Most dishwashers have the thermal fuse located in the control panel area. If this fuse blows, it will need to be removed and replaced to make your dishwasher work. This fuse is designed to blow if the dishwasher overheats. To determine if the door switch is bad, remove the control panel, locate the door switch, and test it for continuity.Īnother part in your dishwasher that could be causing it to not start could be the thermal fuse. This switch is located inside the door panel. If your dishwasher won’t start, then it is possible this switch is bad. This switch is a safety feature and makes it so the dishwasher will not run if the door is open. This door switch is also sometimes called a door lock or door interlock switch. The next thing that could be causing your dishwasher to not start could be the door switch. (To be sure the outlet is getting power you can unplug the dishwasher and plug something else in to be sure the outlet is getting power.) If the dishwasher is plugged in and the GFI has not tripped, then check the breaker on the wall and make sure it has not tripped and is in the on position. If the outlet the dishwasher plugs into is a GFI outlet, make sure it has not tripped.
If your dishwasher does not light up or is not getting power, check where the dishwasher plugs into the wall. Using this guide to troubleshoot your dishwasher works for all dishwashers on the market today. I have not pulled the dishwasher out to check the dishwasher-end of the drain hose.Note: The majority of dishwashers (whether Maytag, Kitchen Aid, Frigidaire, Kenmore, Whirlpool, and Bosch) work the same way. Either that or maybe the pump is faulty? But I can hear a relay in the controller cycling the pump on and off.īy the way, I did check the drain hose connection to my garbage disposal under the sink and it looks fine. I don't know much about dishwashers, but I am guessing the controller is sensing water in the sump, turning on the drain pump, and then maybe sensing an abnormal condition (float switch? pressure switch?) and decides to immediately turn off the pump. I would think that if it is turned on, and senses a condition causing it to cycle the drain pump on and off, I would get some sort of indication. Strange thing is the dishwasher is not turning on any of the lights when I push the ON/OFF button. I can feel the DRAIN PUMP IMPELLER turning. I was able to remove a protective cover in the sump from above the DRAIN PUMP IMPELLER. It will now do this with or without the dishwasher door closed. When I got home from work, I verified that the dishwasher was turning the DRAIN PUMP on and off about once a second, whenever the ON/OFF switch was latched in the ON position. She pushed the ON/OFF button, and it stopped. My wife heard a clicking noise about once a second coming from the dishwasher. I have never really paid attention before.įast forward to this afternoon. I checked the circuit breaker, and then verified 120 V at the dishwasher terminal block (junction box).Īt that time (yesterday), I also noticed the sump was filled with fairly clean water. Normally, the wash selection (regular, power scrub.) light will turn on. Yesterday when I tried to push the ON button to turn it on, nothing happened. It has always worked fine since I moved into this home about 4 years ago. I'm having a strange issue with my Bosch dishwasher, model number SHX43C05UC/50.
