oh... have done this and was not all that happy...
it is on the right wall.. a small chunk of plywood is screwed to the ABS wall on the right up high behind the wet bay controls... the only way I could get to the screws (square bit is required) was to loosen the white control panel that goes across the wet bay and lower it so that I could get my hand/arm in far enough to reach the screws on the far side of the water pump.
I suggest that you PM me your number first... don't remove the entire pump, but replace the weakest link which is the pump switch first. The pump will quit because of the constant cycling and will carbon the switch contacts to the point that the pump will not work.
