Haier Dishwasher Error E1: Drain Error — Not Draining or Draining Slowly

1. SAFETY: Turn off power to the dishwasher at the circuit breaker before reaching into the tub to remove the filter.
2. Check the drain pipe at the back of the dishwasher — straighten any kinks and confirm it has a high loop or air gap before the connection point under the sink.
3. Remove and clean the drain filter: lift out the cylindrical filter from the bottom of the tub, twist and remove the flat mesh filter beneath it, and rinse both under warm running water to remove all debris.
4. Check the drain outlet under the sink — confirm the hose connection is clear and the garbage disposal inlet (if connected) is not blocked.
5. If the dishwasher drains into a garbage disposal, run the disposal for 30 seconds before starting a dishwasher cycle to clear any food sitting at the inlet.
6. Restore power and run a short cycle to test drainage.
7. If E1 returns with a clean filter and clear drain path, the drain pump may have failed.

Error E1 on your Haier dishwasher means: The dishwasher is not draining properly after a wash or rinse cycle. Water remains in the bottom of the tub, indicating a blocked drain path or a problem with the drain pump. The dishwasher's self-diagnostic system has detected this condition and stopped the current cycle.

The most frequent cause is kinked or pinched drain pipe — the hose running from the dishwasher to the drain is bent or crimped. Work through the causes and fix steps below in order — most Haier dishwasher errors are resolved without a service call.

Error E1 is DIY-safe. No specialist tools are needed and the fix typically takes under 30 minutes. Follow all steps in sequence.

The drain filter is the first thing to check on any Haier dishwasher drain error. It sits at the bottom of the tub and collects food particles during every cycle. Cleaning it takes under 10 minutes and resolves the majority of drain errors without any further work.

• Kinked or pinched drain pipe — the hose running from the dishwasher to the drain is bent or crimped
• Clogged drain filter — food debris, grease, and scale have built up in the filter assembly at the bottom of the tub
• Blocked drain outlet connection at the sink or garbage disposal
• Garbage disposal knockout plug not removed at installation — a new disposal comes with a plug that must be removed before the dishwasher drain hose is connected
• Failed drain pump — the impeller is jammed or the pump motor has failed

• Do not run the dishwasher with standing water in the tub from a previous cycle — this introduces bacteria and can damage the pump
• Do not pour drain cleaner into the dishwasher — it damages rubber seals and internal components

E1 returns after cleaning the filter and confirming the drain pipe is clear

• Standing water remains in the tub even after running the drain cycle
• Drain pump is making a grinding or humming noise but not draining

• Clean the drain filter every month — run it under warm water and use a soft brush to remove food residue before it builds up and causes E1
• Scrape plates before loading — excess food in the dishwasher is the primary cause of filter and pump blockages
