Symptom
JennAir dishwasher is not filling
A machine that starts, makes the right noises and never puts any water in — or puts in so little that nothing gets clean. Half of this is under the sink rather than in the appliance.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The supply valve under the sink
Closed, or part closed. Free to check and a genuinely common answer, especially after any work under there.
-
The inlet valve on the appliance
What lets the water in. It fails closed, and its inlet screen blocks with debris from the line.

The float or level sensing
A machine that thinks it already has water in it will not add any. An obstructed float assembly under the tub floor is the usual reason.

Low pressure in the line
A machine that fills too slowly times out. It looks like a broken valve and is a plumbing question.
-
The control never asking
Rarest, and reached by measuring the valve rather than by guessing at it.

None of it needs tools, and all of it makes the visit shorter.
-
01
The valve under the sink
Fully open, and the line not kinked behind anything stored there.
-
02
Run the hot tap
It should get hot within a reasonable time. If it does not, the dishwasher is not the problem.
-
03
Listen at the start of a cycle
There should be an audible fill within the first minute or two. Silence and a running motor is a different diagnosis from a slow trickle.
-
04
Note any code and leave it
A machine that reports rather than simply failing has told you which subsystem it blames. Write it down before you cancel.
-
05
Then book it
Model number, whether you hear anything at all, and whether other hot taps in the house are behaving.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About JennAir dishwasher is not filling
If you are looking up jennair dishwasher no water, this is the page: dishwasher is not filling, what it usually turns out to be, and the check worth doing before anybody is called out in Miami.
The fastest diagnosis is the code
Look under the sink for the dishwasher supply valve — a small shut-off on the hot line — and check it is fully open. It gets closed during plumbing work and nudged by things stored under there more often than anybody would guess. Then run the hot tap at the sink for a moment: if the house has no hot water, the dishwasher has none either.
Half of this is under the sink
Water reaches the machine through a shut-off valve on the hot line, a braided hose, and then the appliance's own inlet valve and its screen. The first two are not the dishwasher and both are reachable with a torch and two minutes. A supply valve that was closed during plumbing work and never reopened is the single most annoying version of this problem, and it is free.
Filling slowly is worse than not filling
A machine that fills too slowly does not necessarily report anything. It runs a long cycle with too little water and washes badly, and the complaint that arrives is "it is not cleaning" rather than "it is not filling". If your cycles have got longer and your dishes worse at the same time, that is the shape of it, and it is worth saying on the phone.

Before you book
Questions about JennAir dishwasher is not filling
It fills a bit and then stops.
That is usually level sensing rather than supply. The machine has decided it has enough — or that it has too much — and stopped. An obstructed float is the common cause, and it is a small repair.
Should a dishwasher be on the hot supply?
On this line, yes, and it matters more than people think. A machine fed cold has to heat every fill itself, which makes cycles far longer and washing noticeably worse without anything being broken. If yours was reconnected during other work, that is worth checking.
It fills fine when I run it right after using the sink.
Then it is pressure or temperature at the appliance rather than the valve, and that is a plumbing question rather than an appliance one. It is genuinely useful information — tell us on the phone.
