My LG model LDF7811ST dishwasher fills with water at the bottom of the dishwasher but water does not come out of the spray arms to clean the dishes. The spray arms are not clogged. I don't get any error codes.

SOURCE: dishwasher powers up when switched

Hi mcdoddle,

I'm Harvey the master Plumber.

Your problem is: dishwasher powers up when switched on via control panel. When start is selected, the lights indicate wash but nothing happens. This may sound stupid but first make sure no one turned the water off to the d/w. If OK then you likely have a clogged or failed solanoid valve. The d/w must be removed for replacement. I don't recomend this for the average homeowner. You might consider utilizing our Repair Directory to find a repairman.

Every time I went to start the dishwasher it went "Ding Ding". I could press every button, turn it on and off OK, change cycles etc. I guessed the sound maybe because it thought the door was open, so set to work pulling it apart. This is how I fixed it.

Make sure you do most of this with the power off - there is probably mains voltage inside!

After pulling off the the cover of the door (with the door open, undo about a dozen screws), the front will fall off if you don't hold on to it, and the door swing closed, so be careful. When it has detached, move the metal part aside, and place the "brains" (circuit board etc) on to a chair or similar so the wires don't stretch.

A quick way to see if you have the problem is the same as mine is to remove the orange cable from the PCB as per below:

Turn the power back on, and press the power button, then the play button, things will hopefully work. If they do, turn it off right away and continue as per below to fix. If you are not worried about the safety mechanism - you could just leave it off and put things back together. However if you forget I think the entire kitchen could get very wet!

Reconnect the orange cable, and start by removing the handle. You will need to disconnect the cable block going in to the back of the handle mechanism, and remove the 3 screws as shown:

Once you have the handle off, remove the metal cover. I found I had to slide it down at an angle and back, ie:

With that off, you should then be able to carefully edge out the reed switch - this is the source of the problem. In the image below the arrow point to TWO hooks that need to be released as you slide it out. I found that the hooks got stuck on the seam as well, so go slowly.

Once you have the reed switch out, you can see if the local electronics shop has one the same (probably the best long term fix), or if you pry it apart, I lightly scraped the contacts inside it:

Once this was done, I could put the handle back together and test (I tested before putting the whole front back on). With a screw driver you can put the mechanism back to "close" the door, and things should hopefully work. Or to "open" the door, pull the handle, and use the screw driver to pull it the rest of the way, ie:

Once you are happy it is all working, put everything back together and things should hopefully be away!

SOURCE: Asko D3230 dishwasher pump will not turn off, with main switch on

This is a anti flood activation. It is a safety device (polystireen float and micro switch at the base of the washer) that keeps the drain motor running due to water leak / spill detection. Dry the water and rectify the leak (normaly pipe or clamp leak) and this should solve the problem.

LD Dishwasher power problem

On the LDS5811 model, I doubt very much that the door switch would cause a full failure.
If you are confident the power is live into the dishwasher, the most common failure with this symptom is a failed controller card (PCB) and will require a service call to LG.

LG dishwasher, LD14AT2

the level switch usually a two-or three inch plastic floating device on the base of the dishwasher that looks like a rounded tube. You should be able to pull the top up and down freely otherwise it may be clogged. If you listen closely, you may be able to hear the microswitch inside click as the unit is moved up and down.
