# Kenmore dishwasher pump replacement

### About pump replacement on a built-in dishwasher

Half of this job is the pump and half of it is the cabinetry: getting a built-in machine out of a run without marking a floor, and putting it back square, level and sealed to the counter. The component is where badge engineering works in your favor — a 665 is a Whirlpool and a 587 is a Frigidaire, and their pumps are mass-market parts on a shelf rather than on a boat, which keeps this well below the same job on an integrated European machine. A 630 is a Bosch, and that is one of the few places on this site where the prefix moves a figure upward.

On this site the job covers dishwashers wearing the Kenmore badge, across Miami-Dade, Broward and Palm Beach. Tell us the three digits before the period on the rating plate when you book: they name the company that actually built the appliance, and on this badge that is where the diagnosis starts.

What this involves

Wash and drain pumps are different failures

Blockage ruled out before a part is named

The builder's own part number, sourced properly

Decide which pump

Water left in the tub is the drain pump. Water moving but nothing getting clean is the wash pump. They are not interchangeable and they are not the same price.

Rule out the blockage

Glass, a fruit stone or a label can stop either one, and a pump replaced around debris fails again within weeks.

Test the motor and its supply

A pump that gets no signal is a control problem wearing a pump's symptoms.

Fit the correct part

Cross-referenced from the Kenmore number to the builder's own. Superseded numbers are traced rather than treated as unavailable.

Full cycle, watched

Fill, wash, drain and dry, end to end, before we call it done.

### It hums but nothing happens.

A pump that hums is being told to run and is not turning, which is frequently something jammed in the impeller rather than a dead motor. That is checked before anything is ordered.

### Is a new dishwasher cheaper?

A fair question and we will answer it honestly. This repair usually wins on a machine under about ten years old and usually loses well beyond that.
