Trouble with Kitchen Aid Dishwasher

Dishwasher Repair

I have the above model kitchen aid dishwasher. I recently had a repair tech out to replace the door switch although had I seen this forum I could have done it myself. The washer has once again stopped working. When the door switch was bad I still had lights on the display panel, now I have no light and no power.

I have been reading the forum here and other places and there has been discussion of the TCO Fuse possibly being the issue. I have removed the door paneling and located the fuse. However the wires coming off the fuse are different than what is being discussed on these forums. My unit has a beige wire going from the door switch to the CON2 connector on the main board and a black with white stripe going to the TCO Fuse which mates with a another black wire with white stripe mid wire that goes somewhere else.

The fuse kit I see online comes with the fuse and two wires with connectors that appear to have wire screws on them. This is nothing like what I have. All the boards I read say the wires MUST be replaced with the fuse. Any suggestions?

Thanks.

Did you check the old fuse for continuity or you are going to replace it just in case?

Whirlpool (the manufacturer of your dishwasher) has redesigned this part. Thats why the wires looks different. It comes with the complete installation instructions.

Here are the break down diagrams for the Kitchen Aid dishwasher Model KUDS01FKSS0

Thanks Gene! I don’t have the tool to do the continuity test. I will check it at work on Monday. Not sure if this is the problem I just dont’ know what else to check. Is there anyting else I should look at as being the problem? Thanks

Temporarily short the fuse with a jumper wire and check if the dishwasher now works.

Thanks richappy. I shorted the fuse and the LED lite sooo I guess the fuse is the issue. I will run the continuity test on the fuse tomorrow just to make sure. I was wondering though, is there something that could be blowing the fuse that may blow the new one when I install it? Or should I feel pretty confident the fuse is the issue? Thanks.

I think the fuse blows at around 14 amps, last dishwasher I checked drew 9 amp with motor and heater on.
I usually assume a power surge blew the fuse, and sometimes the heater or the motor will draw excessive current, best check with a amprobe.

The new fuse worked. Thanks Gene and Richappy!

Well I thought it was fixed. The fuse blew again. Got through one load and it blew on the second. Anyone know what might be causing the fuse to blow? I thought this was to good to be true.

Thanks.

I would buy an amprobe at Lowe’s (worth the money) and temporarily short the fuse. Measure the heater current and motor current. Motor should be around 4 amp, heater around 3 amp. Post results.

If there is nothing wrong with the current drawn by the motor and/or the heater then the water is too hot.

Wow, Gene, that’s a new one on me. Too hot water maybe makes the heater come on too soon??

Could be the motor’s capacitor is starting to breakdown (leak current)

This may sound stupid but does the dishwasher heat the already heated water coming into the dishwasher or is the hot water coming directly from my hot water heater? If the water comes directly from my hot water heater are you saying my hot water heater may be heating the water to much for the dishwasher?

I just ran the dishwasher with a jumper wire to finish the cycle so the water would drane. I then unplugged the main power just to be safe while it sits.
Richappy suggested the Amprobe, I don’t have one and I think this is gowing beyond my ability. If I get an Amprobe where do I take the reading for the heater and motor?
