i get code 4 when i run diagnostic.i know this is fill code.i changed the
water inlet system
the water level switch housing
water valve assembly
and now just changed the control module.it still won`t run a cycle thru.the old module showed 2 hrs on all cycles except rinse and hold and that gets stuck at 8 min.the new module shows all the different cycle time but it only counts down a minute or 2,then the water level assembly then just constantly opens and closes.the plunger just goes up and down every couple of seconds just cycling water in and out.what else can it be?thanks for any help

seen the water fill diaphram fail and cause "surging" of water in, then short pump run on drain and repeat. as for washing and not advancing- check heater relay. water level regulator(includes diaphram part) #263185 $20(need to pull unit and remove left side panel- easy job).

where is and how do i check the heater realay?i already replaced the water level regulator.thanks for your help
