What F3 means (fisher paykel dishwasher f3 error)
On a DishDrawer (model numbers ending in 9), a fisher paykel dishwasher f3 error means the temperature sensor has failed, or the incoming water is hotter than about 65 °C / 150 °F. Keep in mind that the SmartDrive direct-drive motor in these drawers serves as both wash and drain pump, and that F&P’s code numbering shifted between DishDrawer generations, so an F3 is only meaningful once you tie it to your own model. If the home hot-water supply is too hot, fitting a tempering valve resolves it; otherwise the sensor needs testing.
Symptoms of the fisher paykel dishwasher f3 error
F3 is tied to water temperature, so the signs you spot tend to appear around the heating phase rather than at fill or drain. A single clue or a few together can point to either an over-hot supply or a sensor that has drifted, and the fault often shrugs off a reset because the underlying temperature condition has not changed. Line up what the drawer is showing against the list below before you decide between a plumbing fix and a service call.
- “F3” shows during or near the heating phase
- Incoming water may be very hot
- Wash temperature behaviour is off
- The fault recurs after a reset
Likely causes
An F3 splits cleanly into two families: the water arriving too hot from the home supply, or the sensor and its wiring misreporting temperature to the control. Checking the supply side first, then the sensor side, tells you whether a tempering valve solves it or whether a skilled repair and the correct Fisher & Paykel parts are required.
- Incoming water too hot — above about 65 °C / 150 °F
- Failed temperature sensor — the sensor reads incorrectly
- No tempering valve — hot-fill supply is unregulated
- Wiring fault — a degraded sensor connection
What you can check
Because F3 can come from the plumbing rather than the drawer, the most useful owner step is verifying how hot the home hot-water supply actually runs. Take the steps below in order and note your findings, especially the tap temperature, so a technician can judge supply against sensor. Stop short of opening a sealed system, bypassing a safety device, or working on live wiring, and hand those tasks to a qualified person.
- Check whether the home hot-water supply runs very hot.
- Consider a tempering valve if hot-fill water exceeds 65 °C / 150 °F.
- Power off at the breaker for a minute, then restore power.
- If F3 persists with normal supply, book service for the sensor.
Parts a technician may check or replace
Once supply temperature is ruled in or out, a technician may inspect, test, or replace the temperature sensor, incoming water supply, tempering valve, and heating element. For an F3 the chosen part is matched to your DishDrawer’s model and serial number and fitted from trusted parts suppliers, so the drawer reads water temperature accurately again rather than relying on a generic sensor that may track the heat differently. Settling whether the supply or the sensor is at fault before ordering keeps an F3 visit from turning into needless part swaps.
When to call a technician for the fisher paykel dishwasher f3 error
F3 needs a technician to test the temperature sensor and confirm the incoming water temperature. When an F3 persists even though your hot-fill supply is within range, book a visit through our scheduling page and an experienced, qualified technician will measure the circuit and set the drawer right.
Prevention and care
Heading off another F3 starts at the tap: if your hot-fill supply runs above the DishDrawer’s limit, a correctly set tempering valve keeps incoming water within range so the sensor never trips. Keep the sensor connection sound by having any built-in install done to specification, and feed the drawer a stable, correctly rated power supply so the control reads temperature cleanly. If the code returns, record exactly what showed and at what point in the cycle, since that helps the technician separate an over-hot supply from a failing sensor. When wash and dry results suffer alongside the code, treat it as a prompt to book service rather than keep rerunning hot loads.
