How to Replace Older GE Dishwasher Drain Solenoid
On an older GE dishwasher, a tub full of standing water while the motor runs points to a failed drain solenoid, the valve that redirects flow to the drain when the wash motor reverses. Replacing it is an intermediate, 30 to 45-minute job, but first confirm your model actually uses one.
Solenoid or drain pump?#
Older GE dishwashers use a single wash motor that reverses to pump water out, and a solenoid-actuated valve steers that flow to the drain hose. When the solenoid fails, the machine cannot switch from wash to drain and water just sits in the tub. Newer GE units (roughly 2010 on) use a separate drain-pump motor and have no such solenoid, so pull the kick plate and look: a small separate motor on the drain hose means you have a pump (a different repair), while a valve mechanism on the sump near the main motor means you have the solenoid this guide covers. The tech sheet inside the console or behind the kick plate will also list a drain solenoid if you have one.
Before you start#
| Category | What you need |
|---|---|
| Tools | Phillips #2 screwdriver, 1/4-inch hex driver, needle-nose pliers, multimeter, towels |
| Part | Drain solenoid kit for your model (check the tech sheet for the exact number) |
| Time and level | 30 to 45 minutes, Intermediate |
Safety warning: Turn off the circuit breaker. The solenoid operates on 120 volts. Residual water in the sump and drain path will need to be removed.

Step-by-step#
1 - Bail the standing water. Since the machine cannot drain itself, twist out the filter assembly and sponge or wet-vac as much water as you can from the sump.
2 - Open up and find the solenoid. With the breaker off, pull the kick plate (two 1/4-inch hex screws). The solenoid is a small cylindrical device on the side of the sump housing where the drain hose connects, with a plunger that opens and closes the drain port, a two-wire connector, and a mounting bracket or clip.
3 - Test the coil. Unplug the connector and read resistance across the two terminals: roughly 40 to 80 ohms is normal for a GE drain solenoid, an open reading means a dead coil, and a very low reading (under 5 ohms) means a shorted one. Even if it tests good electrically, push the plunger by hand; if it is stuck, replace the solenoid anyway.
4 - Remove the old solenoid. With the connector already off, remove the bracket screws or spring clip, photograph how the plunger links to the drain-valve mechanism, then disconnect the plunger from that linkage (a straight pull or a retaining clip) and lift the solenoid out.
5 - Fit the new solenoid. Set it on the bracket, connect the plunger to the valve linkage in the original orientation, and secure the bracket. Work the plunger by hand to confirm it moves freely and actually opens and closes the valve, then reconnect the wiring.
6 - Test the drain. Refit the kick plate, restore power, start a cycle, let it fill, and press Cancel to trigger a drain. Listen for the motor reversing and the solenoid clicking as it opens the drain path, and confirm the tub empties. Motor and click but no drain means a downstream hose or air-gap blockage.
7 - Verify a full cycle. Run a complete Normal cycle and confirm it fills, washes, drains, and finishes with no standing water in the tub.
Troubleshooting after the swap#
- Clicks but will not drain: the plunger-to-valve linkage is not connected right, or something downstream is blocked. Recheck both.
- No click at the drain step: the board is not energizing the solenoid. Check the connector; if it is good, the timer or board may be at fault.
- Motor hums but will not reverse: that is a motor or start-capacitor problem, not the solenoid.
- Continuous loud buzz: the plunger cannot fully seat, often from debris; clear it promptly, since a buzzing coil overheats and burns out.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.
