What is the Midea Dishwasher E8 error?#
E8 on a Midea dishwasher is a distribution-valve fault: the diverter that switches wash water between the upper and lower spray arms is not doing its job, so one rack cleans well while the other stays dirty. The usual cause is a failed diverter motor or its position switch. A useful clue is which arm is starved — it tells the technician exactly which diverter position has failed.
E8 on a Midea Dishwasher: likely causes and repair cost#
On a Midea Dishwasher, the E8 code signals: distribution valve / spray-arm switching fault.
| Likely cause | Typical likelihood |
|---|---|
| Diverter motor failed | Most common |
| Diverter position switch fault | Common |
| Debris jamming the diverter | Less common |
| Wiring open to the diverter | Occasional |
Typical professional repair: $110–$250 · Difficulty: hard · usually a technician job
Symptoms that often accompany E8: Only the top or bottom rack gets clean; Uneven wash results; Repeated clunk from under the tub
Technician diagnostic sequence for E8:
- Unplug the dishwasher and reach the wash-pump diverter housing from the base
- During a cycle, listen for the diverter to switch flow between the upper and lower arms
- Remove and inspect the diverter flap for food debris or a worn seat
- Test the diverter motor and its position switch for continuity
- Replace the diverter assembly if the motor is dead or the flap will not seat
Parts a technician may check or replace: Diverter valve assembly
Field note: E8 typically shows as one rack cleaning well while the other stays dirty. Note which arm is starved — it identifies the diverter position that has failed.

How to troubleshoot the E8 error yourself#
This is a technician fault, but the observation you make first genuinely speeds the repair. Note carefully which rack comes out clean and which stays dirty across a couple of cycles — that pattern identifies the failed diverter position and saves diagnostic time. Beyond that, the work is under the tub: a technician unplugs the dishwasher, reaches the wash-pump diverter housing from the base, and during a cycle listens for the diverter to switch flow between the arms. They remove and inspect the diverter flap for food debris or a worn seat, then test the diverter motor and its position switch for continuity. If the motor is dead or the flap will not seat, the diverter assembly is replaced. There is no owner reset for a mechanical diverter fault, so hand E8 to a technician once you have noted the starved arm.
Is the Midea Dishwasher E8 error worth fixing?#
Weigh this one on the machine's condition. A diverter-assembly repair runs about $110 to $250, which is fair on a newer Midea and restores even, proper cleaning to both racks. On an older budget dishwasher, a $110 to $250 job is a meaningful fraction of a replacement, so if it already has pump or heater issues I would compare against a new unit. On a machine that is otherwise sound, though, fixing E8 is worth it — a dishwasher that only cleans one rack is not really doing its job, and the diverter is a discrete, well-understood part to replace.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

Midea Dishwasher E8: frequently asked questions#
What does the E8 error mean on a Midea Dishwasher?#
E8 means the diverter that switches water between the spray arms has faulted on your Midea dishwasher. As a result one rack washes while the other is starved, and the control flags E8.
Is it safe to keep using a Midea Dishwasher that shows the E8 error?#
It is safe, but only one rack gets properly clean, so dishes come out unevenly washed. Nothing is damaged by running it, but results will stay poor until the diverter is fixed.
Can I clear the E8 error myself, or do I need a technician?#
This needs a technician. The diverter is under the tub, and testing its motor and position switch and replacing the assembly is a metered repair, not a DIY reset.
How much does it cost to repair the E8 error on a Midea Dishwasher?#
A professional E8 repair on a Midea dishwasher typically runs $110 to $250, covering the diverter valve assembly and the labor to reach it from the base.
Which parts usually fail when a dishwasher throws the E8 code?#
The diverter motor is the usual failure, with the diverter position switch, debris jamming the flap, or open wiring to the diverter next in line.
Is a Midea Dishwasher with the E8 error worth repairing?#
On a sound machine, yes — a $110 to $250 repair restores even cleaning to both racks. On an old budget dishwasher with other faults, weigh it against a replacement.
Why does diverter motor failed trigger the E8 error?#
A failed diverter motor cannot move the flap to redirect water to the other arm. Flow stays stuck to one rack, the control detects the switching fault, and it posts E8.
