What Does Error E1 Mean?

The JennAir Dishwasher E1 error signals a drainage issue, often resulting in water pooling at the bottom and a humming sound. This can stem from improper drain hose installation, a water supply valve being turned off, or a stuck overfill protection float. Addressing these issues promptly is essential to restore normal operation.

Common Symptoms:

  • Dishwasher stops mid‑cycle
  • E1 appears on display when starting a wash
  • No water fill or improper draining

Possible Causes

  • Improper drain hose installation leading to siphoning or poor drain (high)
  • Water supply valve turned off or no water fill detected (high)
  • Overfill protection float restricted or stuck (high)

How to Fix Error E1

DIY Fix Verify water supply and basic setup

  1. Ensure the dishwasher’s water supply valve (typically under the sink) is fully open
  2. Check that the drain hose loop meets minimum height requirements
  3. Look for visible restrictions around the overfill protection float and clear debris

DIY Fix Power cycle the dishwasher

  1. Turn off power to the dishwasher either by unplugging or switching off its breaker
  2. Wait at least 30 seconds
  3. Restore power and attempt to run a short cycle to see if E1 clears

Technician Only Inspect internal drain and water systems

  1. Remove toe‑kick panel and inspect drain hose installation and routing
  2. Check internal drain pump and water inlet valve for proper operation
  3. Test overfill float and water level sensors for correct function
