# Dishwasher error code F3

### What F3 means on this make

The temperature sensor is either not reporting at all or reporting something the control refuses to believe. Like F1 this generation gives no indication at the panel, so it is found in the service menu rather than noticed in the kitchen. A thermistor is a small, cheap part, and it is worth measuring rather than assuming — a harness rubbed through behind the tub reads exactly the same way.

### 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

- Have the thermistor measured cold and its harness checked along its run.
- Where the reading is out rather than absent, the sensor is the part; where it is absent, check the connector before the sensor.

### 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.
