Error Code i20 on Electrolux EDSH4944AS Dishwasher | Causes & Fix

Error i20 on Electrolux : Drain fault — water not draining within the expected time. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. ## What Error Code i20 Means on an Electrolux EDSH4944AS Dishwasher The i20 error code on an Electrolux dishwasher means the machine could not drain the wash water within the allowed time. The control board activates the drain pump and monitors the water level; if water remains above the empty threshold after approximately 3 minutes of pumping, i20 is triggered. ## Symptoms - i20 on the display during or after a cycle

standing water visible in the bottom of the tub
cycle pauses or stops before draining is complete
drain pump audible but water does not move ## Common Causes - clogged filter basket or coarse filter under the wash arms
kinked or improperly installed drain hose
drain hose connected too high in the standpipe (air gap blocked)
clogged garbage disposal or house drain standpipe
failed drain pump motor (normal resistance: 10–30 Ω)
blocked pump impeller ## Tools You May Need - shallow pan or towels
Phillips screwdriver
flat-head screwdriver
multimeter
pliers ## Step-by-Step Repair Guide | Step | Action | Expected Result | |------|--------|-----------------| | 1 | Cancel the cycle and open the dishwasher door. Remove the lower dish rack. Locate the filter assembly at the bottom of the tub (twist and lift to remove). | Filter assembly is accessible. | | 2 | Remove and clean the coarse filter, fine mesh cylinder, and flat filter plate under warm running water. Use a soft brush to dislodge food particles and grease. | All filter components are clean. | | 3 | Check the drain hose connection at the house drain or garbage disposal. Ensure the knockout plug in a new garbage disposal has been removed. Also confirm the drain hose is not looped too high — the high-loop or air-gap fitting must not exceed 20 in. (51 cm) above the floor. | Drain hose routing is correct. | | 4 | If the drain is clear and filters are clean, access the drain pump (usually under the tub by tilting the machine). Disconnect the pump wiring connector and measure resistance. Normal is 10–30 Ω. Replace if OL. | Drain pump condition is confirmed. | | 5 | Inspect the pump impeller (visible with pump cover removed) for debris — a broken glass shard or seed pit can jam the impeller without blocking the hose. | Impeller obstruction is cleared if present. | ## Frequently Asked Questions How do I clean the Electrolux dishwasher filter? Turn the cylindrical filter counter-clockwise and lift it out. Slide the flat filter plate out beneath it. Rinse both under warm water and scrub with a soft brush. Do not use abrasive pads. Reinstall by sliding in the flat filter first, then twisting the cylinder clockwise to lock. Will i20 appear if the garbage disposal is full? Yes. If the dishwasher drain hose connects to a garbage disposal and the disposal is clogged or full, water cannot drain and i20 will appear. Run and clear the disposal, then retry the dishwasher. How often should I clean the filter? Electrolux recommends cleaning the filter every month under normal use, or more frequently if you pre-rinse dishes less often. Can i20 cause damage to the dishwasher? Standing water in the tub can promote mould and odour if left for extended periods. The drain pump motor will not be damaged by a single drain failure, but repeated prolonged pump operation against a blockage can shorten motor life. --- Always unplug the appliance and shut off the water supply before performing any repair.
