Won't drain

Water won’t drain out of tub. This problem previously would correct upon re-running a cycle (bot not this time). I’ve inspected and cleaned the two internal grates, found several small bits of metal in the bottom of the drain outlet. How do I determine if I have a blockage, and remove it? The unit discharges into a sink disposal; the disposal is not clogged. Any ideas would be appreciated! Thanks.

Cannot find any info on the given model number.
GDS comes up as a fridge.
Please check it.

Apologies for my typo on the model number. The correct number is GSD1230X66WW. Thank you.

You may not have a blockage.

I am assuming that you have checked in the sump (Item 505 in Section 4) and this is where you found the metal bits.

Does the wash/drain solenoid (Item 493 in Section 4) pull down when the unit should be draining?
It controls a flapper valve that directs the water up to the wash arms or out the drain.

Does the pump run when it is supposed to be draining?
Does it drain any water out or does it not drain at all?

I have a feeling that the answer to all the above will be yes.

It they are yes, then I would check the piston and nut (Item 564 in Section 2).
Remove the screened cover at the back of the tub.
The piston and nut unscrews.
Check to see if it seals correctly.

If this valve leaks some of the water is directed back into the tub instead of out the drain. It is a common fault with these units.

You are welcome

I saw your thank you in my profile and felt I should warn you about a possible problem you may still have.

If the solenoid was hanging because it had overheated and melted some of the plastic you may need a timer.

The way it works is that at the start of a drain cycle the timer sends power for a couple seconds to the solenoid. It is pulled down and then the water pressure holds it in the drain position till the unit is empty.

Sometimes the timer contacts can stick closed this supplies power to the solenoid for too long of a time and it overheats.

Hopefully it was just a mechanical problem but you may want to keep an eye on it.

Thank you for your followup thoughts, denman. I did not observe any indication of melting, but I’ll keep an eye on it! Thanks again for your expertise.
