Maytag Atlantis MAV8551AWW Over Fills

6 posts in this topic

Checked out a Maytag Atlantis today that over fills the basket on the initial fill.

 

What I've checked so far:

 

When it's filling if I disconnect the power (pull the plug out) the water stops

 

I blew into the pressure switch and it stopped filling and started agitating

 

Took the pressure hose off, blew into it and its nice and clear.  Also, put one finger over the end and blew in the other end no noticeable leaks

 

Initially I was thinking the water valve, but was looking for more input.

These mechanical pressure switches can also fail by either not switching over (problem with the internal switch contacts) or by going out of calibration (deformed diaphragm).  It sounds to me like the pressure switch has gone out of cal.

This implies that the subsequent fills are normal.  Is this true?

Yes, the subsequent fills are normal.  In fact they told me the over fill ONLY happens on the first load after the machine has not been used for a few days.  If they do more loads after the first over fill load the machine performs normally.  I witnessed this myself today.
