Samsung dishwasher repair

On a Samsung WaterWall dishwasher, 7E or 7C means the reflector vane is stuck on its rail. A pot handle, a ladle or packing tape left from delivery is the usual cause, so look before you book.

Six Samsung dishwasher codes and what they point to

Samsung asks owners not to reset or clear a dishwasher code until the cause is dealt with, because the fault stays and the code comes back. Read the code, note it, then work through the step below.

7E or 7C

WaterWall vane cannot travel. Clear the rail, check the logo faces forward and up, then cut the breaker for two minutes.

1E or IE

A clogged fine filter on WaterWall models. On rotary spray-arm models the same code is a heater running too hot.

3E, hot supply

Incoming water is too hot. Samsung's ceiling for the supply is 176°F, so the water heater setting comes first.

4C or 4E

Water is not arriving at the pressure or temperature the machine needs. Valve, supply line and pressure, in that order.

LC or LE

The leak sensor found moisture. The machine powers itself on and keeps pumping out until the water is gone.

PC, PE, bE, 6E

Zone Wash and half load faults, or a button the panel reads as stuck. Touch every key, restart, then call.

What Samsung asks of the water line under the sink

Samsung wants the hot supply between 120 and 149°F and pressure between 20 and 120 psi. Under 20 psi, it says, the fill valve can fail and not close. The hookup needs a 90-degree elbow, 1/2-inch NPT on one end and a 3/8-inch compression fitting on the other, and neither comes in the box. Spotty glasses here are often minerals: USGS found Hawaii public supplies generally under 120 mg/L hardness in its older survey. Samsung also says to shut the valve when the dishwasher sits idle a week or longer, handy for a condo left empty.

Samsung codes

Lift the vane off, turn it around and seat it on the gray shuttle on the rail, so the WaterWall logo faces forward and up. If 7E still shows, switch the breaker off for two minutes. Samsung says a 7E that truly needs service is very rare, and that a visit finding no defect is not covered.
Its touch keys are sensitive, so brushing the panel while loading can pick a cycle that begins once the door shuts.
With a pattern of lit cycle lights, such as Auto, Normal and Express 60 together, or Heavy, Delicate and Quick. Samsung's advice is to treat blinking as a fault only when the dishwasher misbehaves, for example stopping mid-cycle, because lights also blink in normal use.
Loud grinding or buzzing usually means something is caught in the drain pump impeller below the filter. Where the model allows it, clean the filter and the pump opening, carefully, since glass or bone can be sharp. If the pump area is sealed and the noise comes every cycle, it needs service.
No, Samsung says never to use it on the dishwasher; a food-safe lubricant on the hinge is the right choice.

Noise, setup and coverage

Access Point mode, used to pair it with a phone; if you were not doing that, turn it off and on again.
Yes, per model. The DW80CG4051SR sheet lists 1 year of parts and labor. The older DW80J9945US sheet lists 5 years limited on linear motion parts, the circuit board and racks, and a lifetime limited term on the stainless tub and door liner against leaks. Our warranty repair page explains how a covered fault is usually handled.
No. Samsung's drain guide says frozen lines are not covered, and if the sink itself will not drain after running water for about 30 seconds, the problem is the home's plumbing rather than the dishwasher.
Fifteen, with a third rack, an AutoRelease door and a digital leak sensor listed on its sheet.
Often, when the fault is a vane, a filter, a supply problem or a sensor. Many parts come from the mainland, so having the model number ready helps order the right one first time. Our repair or replace guide weighs age against the size of the job.
