Product review (5 stars): Works like a champ
My Maytag front loaded was down and out.  The code was telling me it was either the pressure switch or the pump.  Of course, I replaced the pump first, to no avail.  But, on the bright side, I now have a ready-spare.  The switch was easy to install and got the machine up and running again.  After speaking to a technician (after the fact, of course) I was told that 9 times out of 10, it will be the pressure switch.  So, if you do find yourself in a similar situation, odds are in your favor to replace the switch first.
