Before you book,
in this order.

Each step comes from KitchenAid's own guidance for H2O on its dishwashers. Follow it to the end: the last card says whether this is a visit.

01

Check that someone has not closed the valve under the sink during other plumbing work.

02

Free any bend in the supply hose that could choke the flow.

03

With the water restored, press Start and let the dishwasher attempt the fill again.

04

A repeat with the valve open is a reason to book a visit.

Still there?

It usually turns into fill and water valve repair. Book with the code and the model number.

What not to do

Nothing needs resetting at the breaker for H2O until the supply has been checked; the machine resumes by itself once water flows.

Questions
about H2O.

Can I clear H2O myself?
Check that someone has not closed the valve under the sink during other plumbing work. If it comes back, it needs a visit.
Do I need to reset my KitchenAid after fixing the cause of H2O?
No breaker reset is needed; once water is flowing again, pressing Start lets the machine retry the fill. The cycle carries on from there on its own.
Why would a KitchenAid show H2O after plumbing work under the sink?
The shut-off valve feeding the dishwasher is sometimes closed during other jobs and left that way. A folded supply hose has the same effect, so check both.

Still showing H2O?

Book with the characters exactly as shown, the full model number, and whether any water is on the floor — for a code, that is where the diagnosis begins.
