Viking Dishwasher Code E:05: wash diverter valve problem

What E:05 means

On current Viking VDWU and FDWU 324, 524 and 724 dishwashers, including the water-softener models, E:05 points to the wash diverter valve. This valve switches the wash water between the spray arms. When the control finds a problem with it, the E:05 icon appears on the program indicator, and the wash may stop or reach only part of the load.

Common causes of E:05

Wash diverter valve not moving
Diverter valve connection loose or damaged
Control not driving the valve

✓ One safe check you can try

1. Open the door and spin both spray arms by hand to make sure they are not blocked by a tall dish. 2. Switch the dishwasher off at its breaker for a minute and restore power. 3. Run a short cycle. 4. If E:05 comes back, stop using the machine and call us. The valve is inside the water path.

! Why to stop there

Valve testing needs the tub and lower panel opened
Spray arm blockage is the only owner-fixable cause
We give a written price before work and a 30-day warranty after

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E:05E:05 questions

What does the wash diverter valve do?

It sends water to different spray arms in turn. If the valve stalls, one level may get no water, or the cycle may stop entirely.

Can a large dish cause E:05?

A dish stuck against a spray arm blocks the arm, but E:05 refers to the valve. Still, we check arms first because it costs nothing.

Will the dishes in the top rack be dirty?

They might, because the water may only reach one level. Rewash after a reset if you are not ready to call, and tell us the results.
