Fisher & Paykel DishDrawer Error Code? Causes
Most likely an F1 leak-in-the-base code has tripped the flood switch — the most common DishDrawer error — but F2 points to the wash pump, F3 to a fill fault, the A-series to the heater and sensors, and F9 to an overflow, so read the exact code first, then a Power-button reset before deeper diagnosis.
How DishDrawer codes work#
Fisher & Paykel DishDrawers, on models like the DD24DCHTX9, DD24DCTX9, and DD24SAX9, are two independent drawers, each with its own control, pump, heater, and fill system. Each shows its own F or A code, and because the drawers are independent, one can error while the other runs a normal cycle. The code letter and number map directly to a subsystem, which is what makes these fast to diagnose.
Causes at a glance#
| Code | Meaning | Share of cases | First move |
|---|---|---|---|
| F1 | Water leak detected in the base | 30% | Find the leak; clear the base |
| F2 | Motor / wash pump fault | 25% | Test the wash pump motor |
| F3 | Water fill fault | 20% | Check supply, valve, and hose |
| A1-A4 | Heater or sensor alarms | 15% | Test the heater and thermistor |
| F9 | Overflow detected | 10% | Check the inlet valve and float |

Working through the codes#
F1 — water leak in the base (30%). F1 is the most common DishDrawer error: the flood switch in the base pan has sensed water, and the pump runs continuously to clear it. Find the source — a hose, seal, or spray-arm leak — dry the base, and confirm the flood switch resets. F2 — motor / wash pump fault (25%). F2 means the wash pump motor is not responding or is drawing abnormal current. Each drawer has its own wash pump driving the spray arm. The pump and its wiring are tested and the pump replaced if it has failed. F3 — water fill fault (20%). F3 means the drawer did not fill within the expected time, typically 90 to 120 seconds. Check for a closed supply valve, a kinked inlet hose, or a failed inlet valve, and clear whichever is restricting the fill. A1-A4 — heater or sensor alarms (15%). The A-series covers heating and temperature sensing: A1 for a heater not reaching temperature, A2 for a thermistor fault, and so on. The heater element and the thermistor are tested per the specific code. F9 — overflow detected (10%). F9 means the water level exceeded the safe maximum, so the drain pump runs and the cycle aborts. Check for an inlet valve stuck open or a float fault admitting too much water.
Reset and diagnose#
- Note the exact code letter and number before doing anything.
- Disconnect power at the breaker if you will inspect internal parts.
- To reset, open the drawer fully, press and hold Power for 5 seconds, close it, then open and press Power to restart.
- If the code returns immediately, the underlying fault is still present and needs the matching repair.
- Remember the other drawer can keep running normally while you service the faulted one.

Preventing a repeat#
- Scrape plates so debris does not clog the pump or spray arm and trip F2.
- Keep the inlet hose unkinked and the supply valve fully open to avoid F3 fill faults.
- Check under the drawers periodically for early seepage before it becomes an F1.
- Clean the filters regularly so drainage stays clear.
- Run both drawers evenly so one pump and heater do not wear far ahead of the other.
- Address an F1 leak code promptly before water reaches the base electronics.
- Keep the inlet hose unkinked and the screen clear so fill faults do not recur.
