Major Appliances/Maytag Dishwasher Noise


Subject dishwasher (Maytag MDB9100AWW) makes a hissing sound when the cleaning cycle starts. It sounds like water hissing through an open valve. It lasts the entire cleaning cycle.
I suspect that it may be a defective solenoid valve.
Can you venture an opinion based on the above description.

ANSWER: If a defective solenoid valve, I would venture to guess the unit would overfill and water would start coming out of the dishwasher onto the floor.  To verify, remove the lower and start a cycle.  After the unit has filled, remove the plug going tot he water inlet solenoid.  The noise should stop.  If you still hear it, try to isolate where the noise is coming from.  Could it be something in the circulating pump assembly making this noise?

Waiting to hear from you,
Eric and Ann Campion

Thanks for the usual quick response.....but I need clarification.
What is "....the lower...", and what/where is, "...the plug....."  going to the water inlet solenoid.
Am not familiar with those terms.

Sorry....That should have read lower access panel.  Remove it to gain access to the water inlet valve.  The solenoid your home water supply attaches to is the culprit we are speaking of and want to replace it or eliminate it from being the problem.  There is a two prong plug attaching to this solenoid. When noise starts, unplug this and tell me if the noise stops.
