What Does the F1 Error Code Mean on a Fisher & Paykel Dishwasher?
On Fisher & Paykel DishDrawer dishwashers — including the DD60 series (DD60DCHX, DD60DCW, DD60SDFHX) and the 605 platform — the F1 error code means flood detected. The control board has detected water in the base of the machine where water should not be present. This triggers the flood protection system, which shuts down the wash cycle and activates the drain pump to remove the water and prevent damage to your kitchen floor or cabinetry.
This is a protective fault, not a fill fault. The machine is telling you it has found water in the wrong place — typically the base tray beneath the wash motor and sump assembly. A float switch or moisture sensor in the base tray triggers the alarm when water reaches it.
Important: Error code meanings can vary between Fisher & Paykel models and production years. The F1 definition on this page applies to the DishDrawer series. If you are unsure what your code means, our technicians can diagnose the exact fault on site.
Common Causes of the F1 Flood Fault
Leaking door seal or gasket. The rubber door seal around each DishDrawer can perish, crack, or accumulate food debris over time. When the seal no longer sits flush, wash water escapes past the door during the cycle and drips into the base tray below. This is the most common cause of F1 we see on DishDrawers in Brisbane — particularly on units that are five years or older.
Cracked or split sump hose. The sump assembly connects to the wash motor and drain pump via rubber hoses. These hoses can split at clamp points or develop hairline cracks from age and heat cycling. Even a small crack will weep water into the base tray during every wash cycle, eventually triggering the float switch.
Leaking wash motor seal. The wash motor shaft passes through a mechanical seal to keep water inside the sump. When this seal wears, water seeps past the shaft and drips into the base. You may notice the F1 fault appearing intermittently at first — only on longer or hotter cycles — before becoming consistent as the seal deteriorates further.
Blocked or overflowing sump. If the drain path is partially blocked (food debris, broken glass, a piece of crockery lodged in the sump), water can back up and overflow the sump housing into the base tray. The flood switch triggers even though the leak source is internal overflow rather than a failed seal.
Faulty float switch. The float switch itself can occasionally stick or fail. Detergent residue, grease buildup, or a small piece of debris under the float can hold it in the raised position, causing a false F1 alarm even when no water is present in the base tray.
Inlet valve not shutting off. If the water inlet solenoid valve fails to close fully when the cycle ends or between fills, water continues trickling into the machine. Over time this overfills the sump and overflows into the base, triggering F1.
What to Check Before Calling a Technician
Some F1 faults have simple causes you can check yourself. Work through these steps before booking a repair.
Power off and check the base tray. Turn the machine off at the wall. If your DishDrawer model allows access to the base (check your manual), carefully tilt or slide the unit out and look underneath for visible water pooling. Mop up any water with towels. If you cannot access the base, skip to the reset step below.
Inspect the door seals. Open each drawer and run your finger around the rubber door gasket. Feel for cracks, tears, hardened sections, or food debris stuck in the seal channel. Clean the seal with warm soapy water and a soft cloth. Remove any visible debris from the seal groove.
Check for obvious leaks. Look at the inlet hose connection at the back of the machine and at the drain hose where it connects to the sink waste or spigot. Tighten any connections that appear loose. Look for drips or water marks on the hoses themselves.
Check the drain filter and sump area. Open the drawer, remove the lower rack, and clean the drain filter and sump screen. Remove any food scraps, broken glass, or debris that could block drainage and cause overflow.
Reset and test. After drying any visible water and cleaning the seals and filters, leave the machine powered off at the wall for at least two minutes. Power it back on and run a short rinse cycle. If F1 returns, the leak source requires professional diagnosis — the base tray is filling again during operation.
When to Call a Professional
Call a technician if F1 returns after a reset, if you can see water in the base tray but cannot identify the source, if the door seals appear intact but the fault persists, or if the machine triggers F1 within the first few minutes of a cycle (which often points to an inlet valve that is not closing). Internal leaks from the wash motor seal or sump hoses are not DIY-accessible on most DishDrawer models — the machine needs to be pulled out, laid on its back, and the base plate removed to access the sump and motor assembly.
How We Repair F1 Flood Faults
When we attend an F1 fault on a Fisher & Paykel DishDrawer, we start by confirming water is reaching the base tray and identifying the leak source. We remove the base plate, run a diagnostic cycle, and visually trace where water is escaping. Common repairs include replacing the door seal, replacing sump hoses or clamps, replacing the wash motor shaft seal, or replacing a failed inlet valve.
Our technicians carry a range of commonly used parts on every van. Most F1 flood faults on DishDrawers are diagnosed and repaired in a single visit.

Frequently Asked Questions
What does F1 mean on a Fisher & Paykel DishDrawer?
On DishDrawer models including the DD60 series and 605 platform, F1 means flood detected — the machine has found water in the base tray where it should not be. This is a protective fault that shuts down the cycle to prevent water damage. Error code meanings can vary between models and production years. If you are unsure what your code means, our technicians can diagnose the exact fault on site.
Is F1 the same as a water fill fault?
No. F1 on DishDrawer models is a flood detection code, not a water fill fault. The water fill fault on Fisher & Paykel DishDrawers is a separate code. These are different faults with different causes — F1 means water has been found where it should not be, while a fill fault means not enough water entered the machine.
Can I fix an F1 flood fault myself?
You can check and clean the door seals, clear the drain filter, dry any visible water in the base tray, and reset the machine. If the fault returns after a reset, the leak source is internal and typically requires a technician to access the base plate, sump, and motor assembly.
How much does it cost to fix an F1 error in Brisbane?
Our callout is $219 including the first 30 minutes of labour onsite. Parts costs depend on the fault — door seals, sump hoses, and inlet valves vary by model. Most F1 repairs are completed in a single visit. Seniors, pensioners, and students receive a $20 discount. All prices are estimates only.
