Fisher & Paykel DishDrawer Error Code A5 — Water Not Hot Enough
What this means
Error code A5 on Fisher & Paykel DishDrawer dishwashers indicates the incoming water supply temperature is below the minimum required for the selected cycle. Unlike F3 (heater fault), A5 specifically relates to the hot water supply from your household plumbing. Fisher & Paykel DishDrawers are typically connected to the hot water supply and expect incoming water of at least 120°F (49°C). If the hot water heater is set too low, the supply line is connected to cold instead of hot, or another appliance has depleted the hot water, A5 will be triggered.
Alternate codes: Alert 5, Error A5
Step-by-step fix
3 stepsCheck hot water availability
Run the kitchen hot water tap for 1–2 minutes before starting the DishDrawer. This purges the cold water sitting in the pipes and ensures hot water reaches the unit immediately when it fills. Then start the wash cycle.
If your kitchen is far from the hot water heater, it can take considerable time for hot water to reach the tap. Always run the hot water first.
Verify the hot water connection
Ensure the DishDrawer's inlet hose is connected to the hot water supply, not the cold. Check under the sink — the hot water valve is typically on the left side. If connected to cold water, switch the hose to the hot water supply.
Some Fisher & Paykel models can be configured for cold water connection, but the default setting expects hot water. Check your model's installation guide.
Adjust your water heater temperature
Check your hot water heater thermostat setting. For optimal DishDrawer performance, the water heater should be set to deliver water at 120–140°F (49–60°C). Adjust upward if it is set below 120°F.
Test the hot water temperature at the kitchen tap with a cooking thermometer. If it reads below 110°F, your water heater setting is too low.
When to call a professional
If your hot water heater is set correctly and producing adequate temperature at other taps but the DishDrawer still shows A5, there may be a mixing valve issue in your plumbing or the unit's temperature sensor may be miscalibrated. A plumber or Fisher & Paykel technician can investigate.
