Maytag Quiet Series 300 | Control Board
Although I am not really familiar with working on household appliances I decided to give it a try when the dishwasher at my residence decided to stop working the other day.¬† The dishwasher is a Maytag Quiet Series 300 and was just a little over a year old.¬† The problem began when some of the lights on the front of the unit stopped responding to input.¬† Strangely the Heavy Wash, the Lock (Dry button) would still respond but unfortunately the start and delay buttons would not respond and thus the machine would not start.
After reading a few forums on the web it turns out this problem is fairly common with this model with either the ribbon cable failing with a short, or the control board itself has a short.
In my case the control board had failed.¬† This part can be found online for about 70$.¬† (Control Board)
To gain access to the control board you will need a star shaped screw driver and a socket wrench.¬† Removing the door is pretty straight forward with about 12 star shaped screws holding it in place.
Here is the control Panel.¬† Keys for successful removal: Unhook Power (flip breaker) and make sure the ribbon cable is securely attached.¬† The ribbon cable will fit into the housing and the plastic case can be moved to lock it into place.
Replacement Control Board.
Working Machine.¬† The good news is that this easy repair was successful, my only concern is that this unit will give out again after another year and a half.¬† It appears that perhaps there is a design flaw in the device in which steam from the drying process can work itself into the control panel and short it out.¬† I wonder if perhaps you sealed the control panel box with Silicon if it would increase the longevity of the machine.
