Having problems with your GE 24 in. Profile PDW7880G Built-in Dishwasher ?

Hi, ^The GE dishwasher (PDW788000SS) will not fill in either "rinse only" or "normal wash" modes. The control panel lights up with all functions. After selecting rinse only or normal wash and pressing/holding the start/reset button down for several seconds to reset the unit the drain pump comes on for approx 90 seconds as advertised. Checked the float switch and there is no continuity in any position of the little switch arm and the switch arm has no spring on it. Seems like this is a faile

If this valve is \015\012defective, you need to completely replace it. It's usually located \015\012behind the lower access panel on the left or right side. It's the device\015\012 with the main water line (usually copper) from the house, a rubber tube\015\012 to the dishwasher, and two wires attached to it.\015\012 \015\012 \015\012 \015\012 \015\012 \015\012 \015\012 \015\012 \015\012\015\012\011\015\012 \015\012\015\012\011\011\015\012 \015\012 \015\012 \015\012\011\015\012 \015\012\015\012\011\011\015\012 \015\012 \015\012\011\015\012 \015\012\015\012 \015\012 Float switch\015\012 \015\012 \015\012 \015\012 \015\012 \015\012 \015\012 \015\012 \015\012\015\012\011\015\012 \015\012\015\012\011\011\015\012 \015\012 \015\012 \015\012\011\015\012 \015\012\015\012\011\011\015\012 \015\012 \015\012\011\015\012 \015\012\015\012 \015\012 The\015\012 float switch is a small electrical switch that's located right below \015\012the dishwasher "floor." Above the switch, on the inside of the \015\012dishwasher, is a plastic cylinder that floats up as water fills the \015\012dishwasher.

If the float switch is defective, you need to replace it.
Hi.

I can't see other's comments.

If it is tripping the circuit breaker, then replace the transorb located near to the flood switch. When the transorb is fried it will let power flow in both directions and you get the same as if you have a short. The circuit breaker trips because of an abonormal power draw. A defective transorb may also cause water valve not opening. The transorb is difficult to test in full, but the part is not expensive. Here the replacement. A basic test can be done Ohmming the transorb. If the transorb has less that 100KOhms, then it must be replaced. This is no definitive test, but it will reveal if the transorb is shorted. Sometimes the transorber may read more impedance than this and still be defective.

If you have replaced the float switch check also for eventual shorts to ground. If you have not replaced the float switch yet, test the float switch by jumping its contacts.

Replacing transorb and inspecting wiring in the valve/float switch area will probably fix the fault. If it does not, before replacing the timer board there is need to read voltages to inlet valve while the machine is cycling (after testing or replacing float switch and transorb). For safety reasons I must remind that tests with power on must be performed by trained technician.

Regards.

Ginko.
