5E code. If your dishwasher has been running fine for awhile then throws a 5E code chances are it could be the pump or a blocked hose or filter but chances are its not. 1. Does the code come on after it has gone through the wash cycle and released the soap dispenser? or 2. Does the code show afer 1 or 10 minutes of running without the wash cycle completing, soap dispenser still closed?
Number 1 is easy to check just diconnect the drain hose and run the hose into a bucket to see if the hose or filter is clogged or pump is working. These machines only use about 2 gallons of water and the pressure is very low its easy to do in a bucket. If number 2 occurs, its not a clogged hose or filter or pump issue the machine is not even cycling.
If number 1 checks out ok you have water flow but shuts down and number 2 has occured, its your Case Level Sensor its the electronic solid state float, DD94-01006A its either sticking due to water impurities or its bad.
Its actually pretty easy to trouble shoot or fix. You have two choices but the machine has to come out. The sensor is located behind a metal plate on the lower left side ofthe machine. You can;t miss it it looks like a float, has a black float inside a clear plastic housing and some wires going to it. You can pull it out and clean it (The float should go up and down with no sticking at all). Or just buy a new one $35.00ish and put in. Also check the inlet hose to the float make sure its clear and clean DD67-0057A.
There is one catch to this that can cause lots of grief if ANY water at all comes out of the float while changing it. If any water gets in the bottom of the catch basin underneath, the very very sentive probes will detct it and throw a LE code and the washer will not work. that is not a big deal just need to pull the basin off and dry it out. The smallest amount of water can cause the sensors to react since its a protection system.
Samsung dishwashers are very quite and wash extremely well but there technology and engineering sucks along with their warrenty and repair manuals there are no manuals for the home owner or much for the repair guy.
That float will have problems again and again and again either its dirty or broken and will cause another 5E code situation.
Side note; food grinders in a dishasher are stupid! All dishes places in a dishwasher should be rinsed! A domestic dishwasher should not be used as a disposal. It makes your house stink and tons of bad bacteriea will grow in places you do not want it to, not to mention they are not made to work like you would think.
Best dishwasher with the least trouble, easy to fix, easy to dignose, easy to work on, good manuals, few problems, good warrenty, best built, quite running, washes great, very well engineered is BOSCH.
