What F8 means (fisher paykel f8 error)
On a DishDrawer (model numbers ending in 9), a fisher paykel f8 error indicates an electrical problem — the control has detected a fault in the electrical system. Fisher & Paykel DishDrawer dishwashers use a SmartDrive direct-drive motor as both the wash and drain pump, and the fault-code scheme varies by generation, so always match the code to your DishDrawer model. This is a control-level condition that needs a technician to trace the wiring and board.
Symptoms of the fisher paykel f8 error
F8 flags an electrical fault, so the behaviour you see is erratic operation that survives power cycling rather than a clear mechanical symptom like a leak or a stalled pump. A single sign may appear, or several may show together, and the code often turns up after a surge or supply disturbance disturbed the wiring or board. Weigh what the drawer is doing against the points below to confirm an electrical fault before arranging service.
- “F8” shows and the drawer will not operate normally
- Behaviour is erratic
- The fault persists across power cycles
- It may follow a power event
Likely causes
An F8 traces to somewhere in the electrical path — a degraded wire, a loose connector, an out-of-range supply, or the control board itself. Considering the supply and connections before the board narrows the search and shows whether trained service with the correct Fisher & Paykel parts is needed.
- Wiring fault — a degraded or shorted connection
- Control board fault — an internal electrical failure
- Power-supply issue — an out-of-range supply
- Connector fault — a loose plug
What you can check
With an electrical fault the only safe owner step is a full power-down and restart to see whether F8 clears, since anything internal is hazardous. Work through the steps below in order and note whether the code returns at once, as that timing helps a technician judge how deep the fault sits. Never open a sealed system, bypass a safety device, or work on live wiring — leave the wiring and board to a qualified person.
- Power off at the breaker for several minutes, then restore power.
- Note whether F8 returns immediately.
- Avoid forcing functions while the code is present.
- Because this is an electrical fault, leave F8 to a technician.
Parts a technician may check or replace
After tracing the electrical path, a technician may inspect, test, or replace the control board, wiring harness, power supply, and connectors. The correct part for your Fisher & Paykel Dishwasher is matched from the model and serial number, and genuine components are fitted through trusted parts suppliers rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician for the fisher paykel f8 error
F8 needs a technician to trace the electrical fault in the wiring and control board. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.
Prevention and care
The strongest defence against another F8 is a clean, stable electrical supply: feed the DishDrawer from a correctly rated circuit, guard against surges, and avoid the brownouts that can stress the control board over time. Have any built-in install done to specification so connectors seat firmly and harnesses are not pinched, and keep moisture away from the electronics by attending to leaks promptly. If the code returns after a full power-down, note exactly what showed and how quickly it came back, since that detail helps the technician tell a supply issue from a board fault. Erratic behaviour that survives power cycling is a reason to book service rather than keep operating the drawer.
