20 Most Recent Samsung DMR78AHS Builtin Dishwasher - Page 7 Questions & Answers

I had the LC code flashing on my Samsung dishwasher and my mom also had the same problem with her Kenmore dishwasher! We tried everything everyone has posted and nothing worked!! Turns out it was an easy fix! Just add jet dry to the jet dry compartment on the inside panel of the door to the dishwasher and it worked!! No more LC code and the dishwasher now works fine!! I thought adding jet dry was an option?? Apparently it is a requirement with these new dishwashers!!

Dishwasher Heavy Error Code Repair Samsung - YouTube

The Normal, Heavy and Smart lights will blink when there is low water level in the dishwasher. Check that the sump area isn't blocked from filling with water. Often there is a float inside the tub that can be held down by a utensil that fell under the lower basket. Remove any foreign objects. Then try to run the dishwasher when it is completely empty. The parts diagram for the dishwasher is available here: https://www.searspartsdirect.com/model/60yajq87a8-001482/samsung-dw7933lrabb-aa-01-dishwasher-parts . If there isn't an obvious blockage in the water level monitors, you could have a wiring problem or an issue with the control board that doesn't get the signal for water reaching the desired level. (Note: if the incoming water pressure were too low, only the Smart light would flash.) The manual for the DW7933LRABB is available from Sears Parts Direct on the product page: https://www.searspartsdirect.com/manual/60yajq87a8-001482/samsung-dw7933lrabb-aa-01-dishwasher . The current link to the manual is https://c.searspartsdirect.com/mmh/pd_download/lis_pdf/OWNM/1206228L.pdf . I hope this helps. Cindy Wells

Check bottom pan for water flood switch located there so it’s trying to pump water out check for leak cause or if you are opening door to add dishes while it’s alrea started this could cause water leak dripping down into pan

Just look on the words written fuse to your dishwasher

Check under screen the retention nut for the spray arm must have come loose I’m happy to assist further over the phone at https://www.6ya.com/expert/howard_977676954994c5b2

There is no internal fuse that I am aware of, if it will not run then more then likely the control panel is defective.

I assume it's still under warranty, I would take it back

It’s probably trying to pump water out from dripping pan if you have water leak will activate drain pump by it self turn off water supply and electric maybe need to be pulled out to see if any water on bottom

Check your air gap at the sink. Otherwise there may be something floating in the hose when angled right restricts the flow other times is turnedcand allowed flow.

Water level error. Most likely brake case assy.

Leak error. Code resets after water under unit is dry.

At one of the sites, it is said that this error means leakage. But there is no more information about it. Check or at the bottom of the dishwasher there is no water. Maybe you are lucky.

Check the heating element of your system. Most likely it was the reason.

There is a leak. In the dishwasher there is protection from leaks. If the sensor gets wet, the machine will show you this error. Sometimes leaks may occur due to an oversupply of foam.

Depends on the problem. You can download the manual and "File/Save As" to your Documents folder from here... http://www.manualslib.com/manual/651265/Samsung-Dmb58ahc.html
