What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep running the appliance when water is visible, a leak warning is active, or water could reach wiring or controls.
- Safe next step
- Stop the cycle if safe, turn off water when appropriate, protect the floor, and avoid repeated resets until the leak source is understood.
- 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.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- A water condition sufficient to activate the dishwasher flood switch
- A persistent or hidden flooding condition that requires Fisher & Paykel Customer Care
Basic checks
- Inspect the floor and cabinet edge from a dry position without moving the appliance; if any moisture is visible, keep the dishwasher off and stay clear of the wet area.
- If the water tap is reachable without stepping into moisture, close it; otherwise keep clear and use qualified help.
- Confirm whether power can be isolated from a safe dry position; if the plug, outlet, floor, or cabinet is wet, use a safe upstream isolator or an electrician.
- Inspect nearby plumbing and appliances for an obvious external spill; if none is visible, do not treat the dry exterior as proof that the internal flood condition has cleared.
Reset or retry steps
- Do not restart after F30 while the source, trapped water, or electrical dryness remains uncertain, even though the manual lists an off/on check before escalation.
- Keep the water off and the dishwasher disconnected until Fisher & Paykel guidance confirms that a monitored restart is appropriate.
When to call a technician
- Contact Fisher & Paykel Customer Care for any F30 that persists, returns, or appears without a clearly external and fully contained spill.
- Keep people away and arrange urgent qualified help if water spreads toward electrical connections or cannot be isolated from a dry position.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
FAQ
What does Fisher & Paykel Dishwasher code F30 usually mean?
Guide 591900A documents F30 on these DW60U dishwashers as flooding. Model context matters: F30 is shared by the two models named in user guide 591900A. This record intentionally uses a stricter no-restart boundary until the water source and electrical area are safe.
Can I keep using the dishwasher with code F30?
Do not keep using the appliance until the visible issue has been checked and the relevant safety warnings have been addressed. Water near mains power can cause shock; never touch the dishwasher, plug, outlet, or standing water from a wet position.
When should I call a technician for Fisher & Paykel F30?
Contact Fisher & Paykel Customer Care for any F30 that persists, returns, or appears without a clearly external and fully contained spill. A qualified technician may check Flood-protection system and Internal water path against the model's service information before treating any part as failed.
