What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Record F40 and the full DW60U2I or DW60U6I model without opening panels or moving the dishwasher.
- Observe the floor, cabinet edge and exposed connections from a dry position. If water is present, leave it off, close water only if safe and arrange service.
Applicability
Exact model · Fisher & Paykel DW60U2I and DW60U6I dishwashers · New Zealand and Australia · Official user guide 591900A
This meaning is limited to Fisher & Paykel dishwasher models DW60U2I and DW60U6I in the reviewed New Zealand/Australia user guide 591900A; DishDrawer products, another DW60 model, or another market may use a different code table.
Reset or retry steps
- Switch the dishwasher off and on once only when the appliance, floor, plug, outlet, cabinet, and visible connections are dry and there is no abnormal heat or odor.
- Stop further retries and leave the dishwasher off if F40 returns or water movement remains abnormal.
When to call a technician
- Contact Fisher & Paykel Customer Care if F40 persists after the single documented off/on check.
- Close the water tap and arrange prompt help if water appears, a hose is damaged, or moisture approaches an electrical connection.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- The manual labels F40 as a water-flow error without identifying a failed pump, valve, sensor or control.
FAQ
What does Fisher & Paykel Dishwasher code F40 usually mean?
Guide 591900A documents F40 on these DW60U dishwashers as a flow error. Model context matters: User guide 591900A gives only the label 'water flow error' for F40. This page therefore avoids assigning a specific component or repair.
Can I keep using the dishwasher with code F40?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. F40 is not proof that a particular pump, valve, or sensor has failed; internal diagnosis requires qualified service.
When should I call a technician for Fisher & Paykel F40?
Contact Fisher & Paykel Customer Care if F40 persists after the single documented off/on check. A qualified technician may check the listed symptoms and source guidance against the model's service information before treating any part as failed.
