Runs thorough cycles but does not pump water up to

Is this a new fault or has it always done this? What's the water stream like while pumping out, but before the spin cycle? Noticed any changes? Can you tell if the pump is still working during the spin cycle (hard to tell by listening but try). It should still be pumping during the spin cycle. Sadly for you, reviews of this model are not too complimentary, and help requests cover a variety of faults. Looks like it may be a bit of a lemon.

If the pump is still running during spin, a possible (likely?) fault cause is a damaged impeller, which would make it pump adequately during the main drain cycle, but lose pumping ability rapidly as soon as there was not much more water to pump, and the backflow leakage rate equalled the rate of water collection at the pump inlet. As well, in that scenario, any water still in the drain line would flow back into the drum as soon as the cycle finished.

When I start a new cycle, I first hear the pump run to empty out all remaining water, and after that I hear the motor run for the regular washing cycle, but there is no water in the dishwasher. After a few minutes, the cycle stops, and the washer claims the dishes are 'clean'. When I try starting a new cycle over and over again, about one in 20 times, the cycle will run normally with water. But then the next time, the problem starts all over again. Once a cycle starts correctly, everything works fine, including the rinsing.

Your main switch needs replaced. The motor that drives the switch operates because it goes through the other cycles, so the switch must be bad.

It is likely the water circulation system is faulty. This dishwasher uses a single motor to run the water pump and the drain pump. If you hear the wash pump operate during wash cycle then it is likely there is a blockage in the water circulation manifold which distributes the water through the arms.

If you do not hear the pump operate during wash cycle then the sensor is faulty. The sensor tells dishwasher to switch to drain cycle from wash cycle.

Try following the diagrams at top of this website to get idea of parts.

This is probably okay, you have clock like motions running the motor electric contacts. There needs to be a delay between some cycles or shorting will occur. The motor on some designs, for example. is reversed to pump out water. to have this work long term, a delay is inherent and not a concern.

Start with removing the screws in the bottom of the dishwasher and pull out the filter, etc. Clean everything you remove in a sink and soak in white vinegar anything is coated with minerals.
Inspect closely everything you can now see with a flashlight (watch out for broken glass!) Remove any debris found. Reassemble and test if removing any obstructions found.
If problems continue, run a short cycle and listen closely. When the pump should be running, do you hear the sound/hum of the motor turning (but water is not draining?) If yes, replace the pump motor.
If you hear nothing during the cycle when the dishwasher should be draining, the problem is almost certainly a failure of the timer/controller that controls the pump motor.
Good Luck!

It sound like a pump issue. The pump is attached to the motor and forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher. Look if the pump's impeller (a round plastic fan blade-type of device) spins around. In case it doesn't spin, look if it doesn't blocked or stuck from any other reason. Good luck

If you have either dry bearings in the motor or sticky grease buildup in the pump bearing/seal, it can cause the motor to stick rather than rotate on startup. More likely to be greasy crud buildup. The best you can do without disassembling the entire unit is to circulate a good degreaser product in a wash cycle, such as 409 or PurplePower. On the off chance (very small chance) it would degrade plastic parts, only run degreaser wash cycle for 5 minutes or so before draining it and running rinse cycle.

Jayron, is the motor jogging? start to spin, stop, start to spin stop. If so, your motor is jogging between the high and low start windings. The motor during spin should start on the high speed windings and stay there until most of the water is drained. GE came out with a new motor, harness and run cap because of this. If you have a meter, there should be a white and white/red wire going to the motor. If you have a steady 120V and it's doing this jogging, replace the motor with the kit...Let me know if this the issue, Catriver..post back.
