Maytag Bravos MCT Bleach Dispenser keeps Running
« on: November 13, 2014, 05:36:45 PM »

Recently, the bleach dispenser keeps running even after the cycles is complete for our Maytag Bravos MCT Top-Load Washer (mvwb850wq0).
This happens in some wash modes (Normal) but not others (Whites). When it does happen, the tub continues to fill and I am worried it will overflow if unattended. If I unplug the washer, the water stops running. Plugging it in again starts the flow.

I was able to go into diagnostic mode and manually open and close the valve for the bleach dispenser, so I don't think it's the valve itself.

My thinking is that the control board needs replacing. Any other ideas?

I would check for power at the valve. If its got voltage when it shouldnt, the board has a sticking relay. If water is flowing when no power is applied, you have a bad valve.

Water does not flow when the machine is unplugged.

Is there a way to fix the sticking relay or does the whole board need to be replaced?

Based on what you are saying, I would replace the board. Replacing the relay is possible, but not easy umless you know which relay it is and have good soldering skills...

That sounds interesting. I always find just a sticky valve.

I would think sticky valve too, but he says "If I unplug the washer, the water stops running. Plugging it in again starts the flow."
That nakes me think board..

I ordered the replacement board and have run at least 10 loads without the bleach dispenser staying open.

It really was a weird problem and I appreciate all of your help!!
