# Dishwasher error code F9

### What F9 means on this make

The machine is watching how hard the water is being pushed round and does not like what it sees. Low usually means the pump is not getting what it needs — a partly blocked filter, air in the sump, or a weak pump. High points at a restriction downstream, most often a spray arm whose jets have limed over on this water.

### Where this appears, and which table it belongs to

On the appliance’s own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.

### Which machines this one applies to

DW20.1 platform, 3000-series. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 8 of the appliance types this site publishes — cooktop, dishwasher, dryer, microwave, oven, range, refrigerator and washer — and publishes none at all for commercial line, freezer, microwave, oven, range, range hood and refrigerator. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.

### What to do about it

- Take both spray arms off and check every jet is clear.
- Clear the filter stack and the sump.
- If both are clean, the circulation pump wants measuring rather than replacing on suspicion.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 363-1406](tel:+13053631406) and describe what the panel is doing before booking anything.
