How to Replace the Drain Pump on a GE Dishwasher

GE uses a small drain pump separate from the wash motor, so a drain failure points straight at it once you have ruled out a blockage. Meter the pump before you buy the part, then work from under the kick plate.

Tools & parts#

Safety first#

Turn off the circuit breaker. The drain pump operates on 120V. Residual water will be in the sump and drain hose. Have towels ready.

Step-by-step#

Step 1: Confirm the pump has failed#

First rule out a blockage — clear the filter, sump, drain hose, and air gap. Then start a cycle and cancel after 60 seconds to trigger a drain: a good pump whirs steadily for 1-2 minutes, humming with no flow means a jammed impeller, and silence means an electrical fault. With the breaker off, meter the pump terminals — 5-20 ohms is good, infinite means a burned-out winding.

Step 2: Remove the kick plate#

Kill power at the breaker and remove the 1/4-inch hex (or Phillips) screws at each end of the kick plate, then pull it straight off.

Step 3: Bail the standing water#

Open the door, twist the filter assembly out, and sponge or vacuum the sump dry — the less water in the sump, the less spills when the pump comes off.

Step 4: Locate the pump#

Lying under the opening, find the drain pump on the bottom-left of the sump housing — a compact cylindrical motor about 3 inches across with one 2-pin connector on top and one corrugated drain hose on a spring clamp.

Step 5: Disconnect the pump#

Set towels underneath, squeeze the connector's locking tab and pull it off, then slide the hose spring clamp back with channel-locks and twist the hose free — water will flow, so direct it into the towels.

Step 6: Remove the pump from the sump#

Most GE pumps twist out: grip the body and turn it about a quarter-turn counterclockwise, then pull it straight down. Bracket-mount models use 2-3 Phillips screws instead. Check the sump inlet for lodged glass, bone, or plastic that jammed the impeller and clear it.

Step 7: Install the new pump#

Use the new gasket or O-ring if included, otherwise reuse the old one only if it is not cracked or flattened. Align the mounting tabs and twist clockwise a quarter-turn until it locks (or screw the bracket down), reconnect the hose with its clamp, and click the wire connector on.

Step 8: Test#

Refit the kick plate, restore power, and start a cycle then Cancel/Drain to run the pump. Confirm water is expelled through the drain hose, check the hose and pump-to-sump junction for leaks, and run a full cycle to verify no standing water remains. If water still stands after the new pump runs, recheck the drain hose for a kink and confirm the high loop under the sink has not dropped, since a lost high loop lets a siphon pull water back into the tub.

When to call a pro#

Call a technician if the sump housing is cracked where the pump mounts (it needs a sump replacement), if the new pump runs but water still will not drain (a control-board or check-valve issue), or if you are not comfortable working under the dishwasher.
