Motor starts but no pressure is building in pump at all...what do i need to replace
Water is supposed to flow slightly through the pump without it running
so disassemble the wand and cut on water supply, see if water comes out
of the wand on-off handle. The motor does not have to be running. Got
water flowing? YES - clean out the wand filter or nozzle hole. A
partially clogged filter will prevent hi pressure activation.
NO? disassemble pump and clean out chamber paths.
Also - A pressure pump is not suppose to be running and not used
for over ten minutes. The pump can overheat from lack of water passing
through and damage the pump seals. A clogged wand is the same as not
using it while you try to figger out why it doesn't have high
pressure. I found my clogged filter and stopped up nozzle but
haven't gotten my real high pressure back yet. Sears doesn't sell
the valve seal kit but someone does.
If the
water flows then the flow should be good, if not the inlet valve is bad or there
is dirt in the filter. Also check the flow at the inlet of the water line. What
is most important for the motor to start functioning is that the door switch
must be ON when the door is shut or this will be an error for starting the
motor. The water pressure must be good and the spraying must be seen to be
good. If there is low pumping or pressure then the spray arms will not turn
around to inject with pressure. If so
the pump must be checked for clogging.
