Viking Dishwasher E5 Error Code: Causes & Fix

What is the Viking Dishwasher E5 error?#

E5 on a Viking dishwasher is a motor error: the wash motor is not circulating water, so the wash arms sit still with water in the tub, you hear grinding or humming, and the breaker may trip when the dishwasher starts. The leading cause in the table above is wash-motor failure — but a jammed impeller or a bad capacitor produces the same symptoms, so I never condemn a Viking motor before checking for a jam. The first listen is for a hum without rotation at the start of the cycle.

E5 on a Viking Dishwasher: likely causes and repair cost#

On a Viking Dishwasher, the E5 code signals: motor error.

Typical professional repair: $400–$750 · Difficulty: professional only · usually a technician job

Symptoms that often accompany E5: No water circulation during wash cycle; Loud grinding or humming noise; Circuit breaker trips when dishwasher starts; Wash arms stationary with water in tub

Technician diagnostic sequence for E5:

1. Listen for motor hum without rotation at cycle start — indicates seized motor or failed capacitor
2. Check wash motor impeller for glass or debris jam through bottom filter access
3. Measure motor windings — expect 3-8 ohms across run winding
4. Test start capacitor if motor hums but does not spin

Parts a technician may check or replace: wash motor assembly; motor capacitor

Field note: Viking wash motors are special-order with 2-4 week lead time; verify motor is truly failed before ordering — a jammed impeller or bad capacitor is a faster and cheaper fix

How to troubleshoot the E5 error yourself#

Listen at cycle start: a motor hum with no rotation points to a seized motor, a jammed impeller, or a failed capacitor rather than always meaning a dead motor. The safe homeowner check is the impeller — through the bottom filter access, look for glass or debris jamming it, since that is a common and cheap cause. Clearing a jam can resolve E5 with no part at all. What needs a technician is measuring the motor windings against the Viking spec and testing the start capacitor with a meter, and if the breaker is tripping, that electrical fault should be diagnosed professionally. Crucially, Viking wash motors are special-order parts with a multi-week lead time, so it genuinely pays to confirm the motor is truly failed — a jammed impeller or bad capacitor is the faster, cheaper fix.

Is the Viking Dishwasher E5 error worth fixing?#

E5 splits by cause, and the diagnosis really matters on a Viking. A jam or a capacitor is inexpensive and gets the machine running quickly. A full wash-motor replacement is the top of the professional repair range in the table above and carries a special-order lead time — but even that is a fraction of a new Viking dishwasher, a premium built-in appliance. So the answer is repair, with a strong emphasis on confirming the real cause first. I clear the impeller and test the capacitor before ordering a motor, because most E5 calls do not need the expensive, slow-to-arrive part. Only an old machine with several failures would tip toward replacement.

Viking Dishwasher E5: frequently asked questions#

What does the E5 error mean on a Viking Dishwasher?#

It is a wash-motor error — the motor is not circulating water, so the wash arms are stationary, you hear grinding or humming, and the breaker may trip.

Is it safe to keep using a Viking Dishwasher that shows the E5 error?#

If the breaker trips when it starts, stop using it until diagnosed. Otherwise it simply will not wash, and a motor humming against a jam can overheat.

Can I clear the E5 error myself, or do I need a technician?#

You can safely check the impeller for a jam through the filter access. Testing the windings and capacitor, and any breaker-tripping fault, needs a technician.

How much does it cost to repair the E5 error on a Viking Dishwasher?#

A jam or capacitor is at the low end; a full motor is the top of the professional repair range shown in the table above, and a special-order part.

Which parts usually fail when a dishwasher throws the E5 code?#

The wash motor is the headline cause, but a motor-winding fault, a failed capacitor, or an impeller jammed by glass produce the same code, often more cheaply.

Is a Viking Dishwasher with the E5 error worth repairing?#

Yes — most cases are a cheap jam or capacitor, and even a motor is a fraction of a new Viking, so repair is the right call after confirming the cause.

Why does wash motor failure trigger the E5 error?#

The board watches for the wash motor to circulate water. When the motor seizes or cannot start, it never confirms flow, so the board halts the wash and posts E5.
