The Samsung DMR57LFS Dishwasher has a 15 Amp/250VP Volt Fuse located on the lower right side of dishwasher behind an aluminum panel held by two screws. Pull dishwasher out from counter, remove lower rectangular aluminum panel, and it is just inside underneath. Unscrew fuse holder and replace fuse. I had to pay a Samsung Authorized Repairman $109.70 to replace a simple fuse. I learned the hard & expensive way. Samsung won't tell you to check the fuse underneath the unit. They won't even tell you that there is a fuse underneath on the right side. The fuse protects the Printed Circuit Board or Blue LED Control Panel in the event of a power surge or lightning strike.The less than $4.00 fuse will blow first.
Indicates control hasn't sensed a rise in water temp during heat cycle. Make sure you hear the water being circulated during wash cycle. If so the heater, control board, thermostats or wiring are most likely bad. If heater, therms, and wiring check good its usually the control. When fixed press Heat dry- Normal-heat dry-Normal or High temp- air dry-high temp- air dry to reset control.
Hi, Your problem lies with a hot water problem. The first fill must be between 125-140 degrees. Run your hot water tap for a lot of minutes. Immediately run another load. If there is some improvement, you need to up your water heater temp. a notch or two. On electric, there are two therms, top and bottom, same here. One a quarter run a gallon of white distilled vinegar thru the dw. Hope this helps.
This means you have an open heat circuit. It could be either a bad heating element, a bad hi limit thermostat, or a bad control board. The heater and hi limit therm can be tested for continuity with an ohm meter. Most of these units the heater will come with the control board in a kit. Hope this helps.
A 15amp automotive fuse is rated for a 12VDC system in an automobile, not a 125VAC houshold electrical system in an appliance. I don't think your automotive fuse can handle the start current being drawn by the main wash pump as the dishwasher starts. I would recommend you replace the thermal fuse in the dishwasher with an appropriate replacement BEFORE assuming you have a problem with anything else in the dishwasher.
Some Whirlppol manufactured dishwashers had a noted problem with the thermal fuse. The gauge wire used in the control panel would heat up and cause the thermal fuse to blow prematurely. The manufacture's answer was to provide a replacement kit that you were to splice in place that had a larger gauge wire. The thermal fuse replacement kit for Whirlpool dishwashers can be purchased at any of the following websites:
if the clean light is blinking that mean you dishwasher is having a heater issue. it is an error code. either your control board is bad or the heater or the ntc therm. if you take the bottom panel off you will see or should see a tech sheet that will tell you how to clear the error code or this website will help you. just enter your model number http://servicematters.com/docs/wiring/wiring_main.htm
the p3error is an open or shorted booster thermistor.take off btm panel on the right side is the bstr, do when cold and no power to mach.,TURN OFF BREAKER, ON THE UPPER RGT CORNER OF BSTR YOU WILL SEE THE THERMISTOR.unplug from harness use7/16 wrench to unscrew from bstr. well,get new therm.and installyou can get @ any hobart office in your area, part#328994. dont forget to vote, thanks, monomoy
it could be bad thermal fuse or loose wires in jbox at bottom .to chkd therm fuse remove the screws the on top of the door holding the control panel.then pull out the panel and u should see cntrol board on the rhs of the panel.the thermal fuse is mounted on rhs corner of the control board.remove wires from fuse and chk for continuity.if open replace.if ok remove toe panel at the bottom and remove the screw of j box at rhs bottom corner.chk for loose or burnt wires.do not forgot to unplug the unit from power before doing all this.good luck
You need to test the fuse for continuity using a multimeter tester, if the multimeter returns infinite impedance then fuse is blown and must be replaced, the fuse is not normally glued, but after a short some contact may have melt down and now fuse is soldered. If this is the case, fuse must be unsoldered and replaced. See if you can publish here a picture of fuse.
