Hello,

I am an experienced electronic tech/maker and am not shy about repairing any machine. However, I prefer to gain some understanding of how a machine works before I start tearing into it.

I have a reasonably old dishwasher - it might even be more than 2o years old.

I ran a cycle the other day and it sounded like it always does when I run the dishwasher. There was no obvious sound that would tell me it wasn't working as it did sound like it always does.

However, when it was done, the dishes were just as dirty as when it started and the inside of the dishwasher was completely dry.

I've seen articles on the web that talk about the door switch, the float, the inlet valve, and even the tube that connects to the vent at the sink.

I'm thinking that the door switch is probably not the problem, since the dishwasher does run and it is my feeling that a broken door switch would most likely prevent the unit from starting a cycle at all. This leaves me with the other three options.

My gut feeling is that I should be looking at the inlet valve and either testing it to see if it's working at all ... checking the wires for proper connection etc. or possibly just replacing it outright.

Are my thought processes here moving in the right direction? Any advice before I open this thing up and investigate?

Thank you,

Mike

Hi Gene, thanks for your reply.

As far as the actual model number, I'm not quite certain... however, I can offer you this photo that I just took...

You may want to check the float and the float switch (#32 and #30 on the diagram).

Wouldn't a damaged float still allow water to get into the machine? Or does the switch that the float actuates, break in the "on mode" causing the machine to believe that the float is at the top therefore it won't take on any more water?
