20 Most Recent Samsung DMR78AHS Builtin Dishwasher - Page 4 Questions & Answers

SE is a drain error, usually associated with either a blocked or kinked drain hose, the drain its self being blocked or the empty pump failing.

LE is LEak warning. There are areas in the base of the machine where leaking water will pool and be registered by a sensor which will cause the error to display and shut the machine down to make it safe.

Not wishing to impugn your repairer's integrity or competence, but I would guess that you started with a faulty pump or drain pipe, he has cured the problem but not tightened up a seal which is now leaking and causing the new problem.

Short of a fantastically unlikely coincidence, I cannot imagine a scenario where the new problem would not be down to poor work by the original repairer. He needs to come back and fix his poor workmanship.

Hi suzyb3,

DISHWASHER NOT CLEANING PROPERLY...

Kind Regards :-)

Hi

The issue is with the water not draining as something might be blocking the drain pump assembly thus the water is leaking. To solve this issue you'll have to take the front lower access panel out and then clean the drain pump assembly completely, also clean the impeller and chopper assembly located at the bottom of the unit. After this is done the issue should be resolved, if not then check the float switch mechanism and make sure that is fine. Hope this helps...please post back for further assistance.

Hi, the HE codes refer to temperature errors. The HE codes refer to heater problems. These are all functional errors that require a certified service technician, but disconnecting the circuit breaker in the meantime can prevent the problem from growing worse.

Sounds like the theromstat is shorted. Download the manual from Samsung before you try to replace.

Hello, Welcome to FixYa. I read your post and having changed a few of those myself and since you asked for "ideas" I do have an idea that comes to mind but first I need to know, are you attempting to snap the stainless steel ring under the filter ? Is that indeed what you are referring to ? In my experience and according to my samsung service manual, that piece must go in before or at the same time as the mesh filter assembly, but it wont go in after...not sure if you knew that so I'll watch for your reply and go from there...if need be. Regards, Macmarkus :) Regards, Macmarkus :)

Hi,

That is not that hard to fix and you can easily buy the parts yourself online...Here is a tip that will help you with the online buying...How to Buy Appliance Parts Onlineheatman101

You didn't say, but is the drain hose connected to a garbage disposal? If so, is the knock-out removed?
Is the pump running or trying to run? Any kinked houses internally or externeally? Is the pump or screens plugged? Does it work without detergent?

Hi,
Check under your dishwasher usually on the front left corner... there are just acouple of screws and a couple of hoses to change to replace this.. actually a fairly simple deal.
Just check out my tip for how to buy parts online and the tip on the valve...

If it rubs against the cabinet that its under there should be two clips that are attached to the top of the washer and is screwed to the underneath of the counter top. Take the screws out of clips and counter top and you should be able to move it enogh to fix the probels.

THE WATER LINE TO THE DISHWASHER SHOULD BE FROM SAME HOT WATER LINE TO THE SINK. RUN THE HOT WATER IN THE SINK UNTIL HOT THEN TURN ON DISK WASHER AND CHECK THAT THE TEMP IS CLOSE TO SAME TEMP. HAVE SEEN COLD WATER LINE USED. YOU SHOULD BE ABLE TO SEE WHICH LINE THAT THE WATER LINE TO DISHWASHER IS CONNECTED.

It is probably in timer mode. Consult your user manual.

First things to try: 1. Unplug the fridge and move it away from the wall. 2. Inspect the power cord for damage. Replace the power cord if it is damaged. 3. Plug the fridge back into the wall outlet. 4. Set the temperature control to the desired level. 5. Push the "Reset" button, located near the temperature control panel, to reset the temp control settings. The Reset button is usually red in color. 6. Move the fridge back to its original position.

Incoming water temp or pressure is too high

I would check the drain itself. Make sure there aren't any eating utensils getting caught in the drain area.
