First of all, new member, and thanks for having me.

I have an ‘80 GE 2500 dishwasher that my significant other wants to replace because of this Ld code being displayed...”said” it didn’t do the dry cycle. I really would like to keep this machine as it is truly robust, useful and a stylish modern antique. We’ve been using it more since Covid-19. Last night I turned off the circuit breaker for about a minute, and this morning I cleaned the float as it had some greasy crud built up on and around it. I know, kinda gross, should’ve done it sooner. I turned it on and a few minutes later the Ld displayed, however, it’s still continuing the 96 minute wash with no apparent leakage underneath. There was a strip of plastic film on the bottom of the door, visible from the inside with door open that was coming loose. One half is still there. I wasn’t sure if this was never removed after install, maybe a leak recall remedy or something the previous, and original, owner stuck on it. Whom, by the way, was an engineer for GE at Appliance Park who passed away with several lucrative patents including spine fin tubing. He was a real cobbler too with a frequent disregard for aesthetics as well!

Anything else I can check or should we start shopping?

not sure but...

 LD may indicate a leak was detected but since the machine probably does not have a drip pan under it, maybe it will trigger if it sees the water level drop down for any number of reasons.
The motor seal could be leaking, the drain solenoid may be sticking open and allowing water to drain out while the motor is running. Listen to the drain in the sink for the sound of water draining. The drain is closed by a lever acting on a linkage with a rubber stopper inside the pump body.( Sears.com/parts) and check the parts breakdown on your exact model.

The fix may be really simple and you may get some more years put of the machine.

I don't know how much this helps you, but that is where I would start. And maybe you should check under the machine ASAP just in case there is an actual leak. You don't want to damage anything under the machine, in your kitchen or the space below it.

Ld stands for a long drain. The dishwasher is taking longer than normal to drain. This could be due to a kinked drain hose or a blockage in the drain hose. The electronic control is sensing this and is sending the fault code to the display. See the attached pictures for an explination of how this works. The dishwasher will continue to run through he cycle but there will probably be water in it at the end. Check to be sure the drain line is not kinked. If it’s OK then you will have to disconnect the drain hose from the pump and the sink outlet and determine if it is clogged.

Good luck and keep us posted. These are relatively good dishwashers that clean very well.

Sorry, I can’t seem to get the pics to not rotate.

Most likely the piston is bad, that will cause the machine to drain slow or not drain at all. Very simple part to replace, it is located inside the tub, against the back wall at the bottom you will see a filter screen held in with 4 1/4" screws, under that filter strip in the middle is a round device called a piston, that simply unscrews and you will probably see the rubber valve is probably deteriorated. Good Luck, it is a great machine.

In addition of checking the drain valve piston be sure that the Airgap [ if used in your home ] is not clogged partly.

Oh the memories!

 My parents had one of these machines and now that you mentioned the "Long Drain" error, it brought me back to a time when their machine was doing the same thing!

I checked those obvious things mentioned and still the problem persisted. I wound up pulling the machine out and found that the drain hose had kinked at the top of the cabinets. The machine was installed with the hose going up the left side of the machine over the top to the right and then over a cabinet draw and then down into the sink area to the disposer. That satisfied the siphon break I guess in the installer's eye. He used a thin walled rubber hose that ran between between the counter and cabinet wall. Eventually, it sagged and kinked where the hose went over that wall.I pulled out the hose from the disposer and off the drain valve and found debris had accumulated at the pinch point. It was never an issue before.

Some questioning revealed that my father had loaded the machine without scraping the dishes first and somehow managed to dump some peppercorns into the machine. They worked their way past the filter and the sizing plate in the soft food disposer and got pumped into the drain line, preventing the machine from draining completely.Once I cleared out the hose and rerouted it, they nave had another problem with the machine.

My mother had always had Kitchenaid machines and really did not like the GE so I came into a nice Maytag Jetclean machine and she opted to take that in its place. She never looked back and always said how much better the Maytag was. It was easier to load and cleaned the dishes much better.

I had a similar thing happen, we plumbed a dishwasher (either a GE or KA) into a disposer (as one does) and used a neoprene reducer (the stepped design one). After several years, the d/w wouldn't clean any more and we found that the weight of the hose had kinked the reducer so it wouldn't drain so well. Learnt my lesson.

Finally messing with this. All of my hoses look ok, not kinked, crushed or any thing. And I’ve blown easily through them all with no apparent blockage. The aforementioned plunger in the back’s rubber is pretty crusty, compromising movement. I’ve ordered a replacement. I cleaned the screen and the little flapper while I had it off. Pretty gross. Also, the check valve at the front of the machine had the rubber flap inside all balled up. Found one on eBay and it should be here in a week or two. Hope it all works out.
