DISHWASHER TWO PROBLEMS THAT MAY BE RELATED 1. THE WATER DOES COME IN AND DOES DRAIN OUT BUT DURING THE ACTUAL WASH CYCLE THE WATER DOES NOT COME THROUGH THE SPRAY ARM AND THEREFORE DOES NOT TURN. DURING THE WASH CYCLE THE DISHWASHER IS NOT MAKING A NOISE. 2. THE DETERGENT DOOR ALSO DOES NOT OPEN UP DURING THE WASH CYCLE. ANY IDEAS.

Faults not related i would think is there a low humming noise when supposed to be wsahing? if so this is the motor capacitor faulty in all probability. this is a cheap part and easy to replace. otherwise, check if power to pump. if no power then points to a module fault. if there is power, points to a motor fault

Con you check to see if the insulation over the top and sides of the dishwasher was touching the floor and wicked up enough water to get wet? That would reduce the sound dampening characteristics. It is also possible that the hose being shaken off was caused by an issued with something jamming the pump; check the drain grates to see if there is anything you can pull out.

I have a whirlpool Adp8540 that seems to go through the wash cycle completely but when we open it up the water has not gone through the spraying arms and the soap is a solid mass at the bottom of the...
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.

I have got DWN 38 L Bendix dishwasher, problem is that during the wash cycle water starts to come under the washer. To ,me it looks like it can't take the water out.
If water is collecting under the dishwasher then there could be a few reasons.
1. door gasket is leaking - check for defect and replace if required
2. the wash or drain pump could be leaking water. Seals are not sitting properly or drain hose is cracked.

What does U3 mean?
U3 can mean quite a few things depending on when it occurs and which drawer it is.

It could mean Lid fault and will show up as soon as you start dishwasher.

It could mean drain problems if it occurs later in the wash cycle and there is water left behind.

It could mean the wash arm is not sitting properly if it occurs during wash cycle.

Top drawer retains about 2 inches of detergent water and dishes don't come out clean (sometimes). It also makes a loud noise during wash cycle. Drain hose is not kinked.

Not cleaning fully - tablets left in bottom of unit - some of runners on bottom tray missing
Hi there,

Well first of all you can check the Water-inlet valve
Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it. When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need replace it.
After then you can check the Drain valve,  that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.
Please post comments if you need more help or information..............

Good Luck!!

Thanks

LG LD-4050W dishwasher shows an E 1 fault, but no leaks found, and soloniod checks out ok?
When no leaks are found and you are getting an E1 error, the most common reason is that two things are true.

1.) The dishwasher drain hose does not connect to an airgap valve before it connect to the garbage disposal (or drain connection)

2.) That same drain hose does not have a high point in the hose between the dishwasher and the drain. This allows a natural siphon effect to pull the water out of the DW during the wash and rinse cycle.

The best solution is to install a dishwasher air gap on your sink and connect the drain hose to it and the air gap to the actual drain. They are almost free and any real hardware store.

But if the air gap is not possible, lift the drain hose as high as possible under the counter top and attach it so it stays up there.

Please report back with what you find. OK?

Loud humming noise when dishwasher is filling up with water
your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.

there are two components that start before the circulation pump.(wash noise you hear)

first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.

the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..

Water leaking from dishwasher lg model lds5811ww
The drain line is clean. Have you checked to make sure the the rest of the drain is clear all the way down to the main drain?. Also check the pump to make sure that it is working properly, it might be pumping water in, but it may not be wanting to pump the water out

Frigidaire FDB421RFS3 Dishwasher:No water sprays through top arm Water flows through the bottom arm allowing it to spin freely and clean dishes. However while running, I observed that the top arm receives no water at all. There were no clogs in the upper arm supply tube and the motor-pump seemed to run adequately. From what I've read, the motor-pump supplies both lower and upper arms with water by intermitently operating, allowing a check ball to alternate positions between both inlets. Any ideas on the problem and solution ?
