I need help with my dishwasher

3

Hey there! Thanks for providing the model number and explaining what’s happening.

On your Samsung dishwasher DW80J3020US, the Auto and Heavy lights blinking together indicate that the dishwasher has detected a problem and stopped the cycle.

Since your dishwasher appears to fill with water, runs for about five minutes, and then stops with both lights blinking, we’ll want to check for a possible water-level or water-supply problem before replacing any parts.

Here’s what I’d like you to check

  1. Reset the dishwasher. Turn off the circuit breaker for about five minutes, then restore power and start a normal wash cycle.
  2. Listen for water entering. Does the dishwasher fill normally, or do you hear it trying to fill without much water entering?
  3. Check the water supply. Make sure the shutoff valve under the sink is fully open and the supply hose isn’t kinked.
  4. Check for standing water. When the dishwasher stops and the lights begin blinking, open the door and look inside. Is there water in the bottom, or has the dishwasher drained completely?
  5. Listen to the wash motor. After filling, you should hear water spraying around inside. If you only hear humming or a quiet motor, that could help narrow down the problem.

What the blinking lights mean

I checked Samsung’s information-code chart for your exact model. Auto and Heavy blinking together means an over-level water error. The dishwasher believes there’s too much water inside.

Possible causes include a restricted drain hose, a drain pump problem, an inlet valve that isn’t shutting off, or a faulty water-level sensor.

Because this is an overflow warning, turn off the dishwasher’s water supply and circuit breaker until the cause is identified. Don’t continue resetting and running cycles if the water level is too high.

Two questions to help narrow it down

  1. When the lights start blinking, is there a lot of water standing in the bottom of the dishwasher, or is it nearly empty?
  2. When the dishwasher stops after five minutes, do you hear the drain pump running, or does everything go quiet?

Those two answers will help us determine whether to investigate the drain system, water inlet valve, or water-level sensor first, without purchasing unnecessary parts.
