SOURCE: bad smell from my samsung dmr77lhs dishwasher what to do?

Put about three or four drops of eucalypt oil into your dishwasher and put it on a wash cycle - you don't need to use the drying cycle. Then is should smell beautifully. It's probably just the newness of the machine with seals and parts all giving off the smell. If that doesn't work contact the dealer and get them to find out what it is. After all you paid good money for it.
Good Luck

Samsung dmr77lhs dishwasher not turning on


Make sure power is present to the dishwasher from the wall plug, then if that is ok you most likely need to replace the control panel assembly. Cost about $200 US installed on average

How do I fix -no power issue on my samsung dmr78ahs dishwasher?


To eliminate a dishwasher problem, run a heavy 3 pronged extension cord from a known working outlet to the dishwasher and plug the dishwasher into the cord. If you still have no power (dishwasher is not showing any signs of life) then it is a dishwasher problem (circuit board, bad connection from dishwasher cord to dishwasher, etc).

If the dishwasher actually shows signs of life, then you may have a tripped breaker. Check the breaker to make sure it is on and that the tab is not either in the center or the off position. Also, try moving the dishwasher cord's plug from the outlet it is currently in to another outlet in the under sink area. There is a chance that the plug got switched from the normal outlet to the outlet that controls the garbage disposal, that outlet should only be hot when the disposal wall switch is flipped to the on position.

Light panel fully lit stopping program selection and start does a electronic part need replacing


I would suspect the user interface panel.

Most dishwashers can be tested thusly:

Turn off power to the dishwasher at the circuit breaker box. Take apart the Dishwasher door and unhook the cable from the User Interface panel to the main control board. Then, turn the power back on and close the dishwasher door so it latches. The drain pump should go on. If it doesn't the main board is bad. If it does, it's the user interface panel.

Washer doesn't start / lights up. Breaker is OK, electrical outlet too... What could be the problem ?? Control Board.. Fuse


More than likely it is the computer board. However it can be also caused by the main power switch or the door interlock switch. There is no fuse, the main power supply is part of the computer board. The switches are very easy to check but the front display panel of the dish washer needs to be disassembled as access to the main computer board is required. A multimeter it is also required for the switch verification. Make sure the main power cord of the dishwasher has been unpluged. Removing the front display panel it is not difficult. Once the front display panel is removed you have access to the main power switch and the door interlock switch. Unplug the power cord from the dishwasher and remove the connectors from both switches. Verify continuity on both switches using the multimeter. If you have electronics back ground skills you can also verify if the main computer board has power; for this you need to have both switches connected and the door interlock switch latched. You should be able to measure 110 volts AC on the two wires comming out of the main power switch connecting to the comptuter board.

Good luck!

My Samsung DMR77LHS dishwasher has lost power completely near the end of a cycle. About an inch of water remains. I have power to the unit. I checked the 15 amp fuse in the unit - it had blown. I replaced...


Hi, whenever a fuse of that magnitude, or any fuse really, Blows, you should never just replace it, as to have any device, blow a fuse, trip a breaker, requires a major fault, they do NOT blow spontaneously ever. So you have had a major short circuit inside your machine, at some stage, usually this is in, the main Controller Board, most likely the bridge rectifier has gone short circuit, or a capacitor, But it could be anything even the motor?anything like this then will blow the fuse. The reason the fuse blow is to prevent a fire and explosion or both, as if an unlimited amount of current could be drawn, it would be catastrophic, so a fuse blows to disconnect the power. The Cause of this MUST be discovered before one ever attempts to replace the fuse. Luckily, it seems in this case the fault has blown an open circuit on the main Board, and this has prevented any further trouble.
Really after such an event as this one should engage the services of a professional, as anyone untrained may mis something that later on my even prove fatal. Get this unit looked at by a professional service person, ask for a 'Quote" if concerned about costings, then you can make an informed decision as to what to do.

No power


Hi,
The main PSU is part of the control board. You may be lucky to find an aged fuse to replace, but it's more likely a power transistor that's fried.

Unplug and remove the control board to see which bit's toasted. Chances are it's cheaper to replace the control board - but check the probable cause - the motors are not short circuited.

Samsung DMR77LHS Dishwasher has power to dishwasher, ciruit breaker is on. Lights on door will not light up, nothing will work


This does sound like a problem with the "anti-flood" device that does detect water (leak / spill) at the base of the washer. This device is a protection device that consists of a polystirene float and a micro swithch. Once a water leak od spill is detected it automatically puts the washer in pump out mode. You need to determine if a leak exists that has caused the float to trigger the micro switch and clear the water / leak. This should put the washer back to normal.
