LG LDS4821ST Stainless Steel 24 in. Built-in Dishwasher - Answered Questions & Fixed issues

We have a Candy CDI2012/E-02 32900347 1330 3315 dishwasher from around 2013 that once stopped working about 3 years ago. A constant beeping signaled the problem after trying to initiate the washing cycle. Not remembering the details, replacing the controller card (~€50 ebay) fixed the problem at that time. Now we had a problem again, similar to the one above. Once any of the programs was started, the dishwasher would first drain any remaining water (if detected any), then fill for a few seconds, then start draining/refilling again for about 3 times in a row until the controller detected there was something wrong. Again, everything stopped with a constant beeping. Replacing the controller card did not help this time. There were actually two independent problems: We noticed that the inlet water hose was kinked. Thus, only little water would enter. Straightening the hose did not solve the problem, though. We then thought it may be the flow meter. But it is extremely simple in this machine, turned nicely and did not seem to be the culprit. However, we noticed some deposits in the water reservoir that also connects to the inside of the dishwasher. These calcareous deposits apparently clogged one of the channels. This may have induced some pressure difference, which the controller apparently interpreted as some water level problem. Unmounting the water reservoir with the built-in impeller, dissolving the clogging with toilet descaling agent solved the problem: the dishwasher is working again. Actually, no electronic parts had to be replaced.

The check valve prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. If the check valve is stuck closed, try cleaning it out and then replace it if necessary.

Since you have replaced the water inlet valve and still have the 1E error code, this leads me to believe that your water pressure could be too low. 1E error code means that your machine is not filling with enough water to operate correctly, so check the supply system completely and also the filters where the supply hose enters the machine. The poor cleaning could be food clogging the lower filter screen, the groaning is the circulation pump cavitating.

Fill machine with water and let it start to run---then hit cancel button. Dishwasher should go into a drain cycle and then end.

If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work. The thermal fuse is usually located in the control panel on the control board or mounted to the bottom of the tank behind the lower panel. The thermal fuse can be checked for continuity.

Element? You need to make sure it's not running your garbage disposal or anything else. Also it couldn't hurt to pull it out, turn it on it's side and take off the base plate. These machines are notorious for leaking into themselves and rusting themselves out at an early age. LG won't help you if it's rusted. Well, they prolly won't help you anyway but if it's rusted, they won't honor any warranty and you'll never get resolution because the CSRs are the only ones empowered to make the decisions. These usually don't completely break until the machine is out of warranty. Call LG sooner rather than later if you're still in the warranty period.

No they don't do they. Even if you don't use "Sanitize" or "Air Dry". The water doesn't get that hot either if you haven't noticed. With the new "replacement" machine, even after it's done I can't touch the dishes for several minutes. But the LG made that little jingle indicating it was done. There must be an easter egg somewhere that tells the machine to dry. Whatever you do, go and buy Dishwasher Booster, whether your store carries "Affresh" or the Oxy Clean brand, use it every cycle with your washer. You'll thank me. Your problem probably isn't listed under troubleshooting either is it? Just hang some paper towels or a dish towel nearby and expect to dry your dishes when the machine is finished washing them.

des ja vu.... all over again

You must have some wild kids! :)someone must have sat on it and bent all the metal inside bad. Unscrew the panels and try to bend everything back (though it may leak all over from now on if it isn't perfect).

Could it be the water is not getting to the machine? Usually there is a water inlet fitting on the back or bottom of the machine. Please check that first. Be blessed.

Take the front door cover off use a Phillip screwdriver, screws are around the edge on the inside. Be careful the SS is pretty thin and you don't want to bend or dent it. What I found was a little rubber hose that connected to the top of the plastic air duct work and ran down back into the tub. This hose was restricted causing water to back up and then leak down the duct work on to the floor. Solution is to remove the hose from the plastic duct work,blow the hose out to remove the obstruction and reattach the hose.

you can just replace the gasket and you can use a tube of pool lube its a thick gel that protects it and will hold it in place

Water-heating cyclethe wash and rinse, depend of the preheating elements: heating elements and thermostat, test see how to do it. Timer> test the defective timer, clean contacts, with special spray, tigh the wires for loose, breaker, or burn. see the diagramthe motor: see the input voltage motor see the w.diagram

Dear Sir:

LG lds4821 overheats filter board and burns it. Probably another part shorts and causes excessive current. Replacing the filter board makes dishwasher run but problem persists

I have the same problem with model # lds4821ww. Seems the diaphram on the fan housing get dried out and causes it to leak down thru vent tube. Easy to repair just have to get part.

OE means the machine has sensed slow to drain condition.Check out website below,
Most likely food debri in drain hose.or air gap.
Disconnect drain hose from sink and blow a little compressed air into it to shake things up.Run a rinse and drain with hose disconnected into bucket to see whats going on.Trap on sink may be restricted as well.

Hope this helps
