Error codeE3
ApplianceDishDrawer Dishwasher
Quick answer
E3 is a temperature sensor fault tied to incoming water over 65 C (149 F).
Model compatibility: Fisher & Paykel reuses codes across series and model years, so E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Fisher & Paykel lists E3 as a temperature sensor fault and says a tempering valve may be needed to keep incoming water below 65 C (149 F).
E3 and its built-in hint
Among the E-codes, this one carries a practical pointer. The DishDrawer guide names E3 a temperature sensor fault and adds that a tempering valve may be needed on the water supply, so that the water entering the dishwasher stays under 65 °C (149 °F).
Role of a tempering valve
Such a valve blends cold water into a hot supply, which stops the water arriving at the appliance from going over a chosen temperature. Fitting or adjusting one is plumber’s work, and changing the water heater is likewise something a homeowner should not do.
How to handle an E3
Quiet the beeping and write the code down.
Turn the dishwasher off, count a few seconds, and turn it on to reset it.
With E3 cleared, watch the following cycle. If it comes back, stop restarting the machine.
Consider the hot water setting. A heater set very high is worth mentioning to the technician when you phone.
If the code persists, take the power off, close the water supply, and contact Customer Care.
Both temperature scales
The guide states the limit in Celsius and Fahrenheit (65 °C and 149 °F), so it is easy to compare with a figure from your water heater or from a plumber.
Caution with hot water
At 149 °F and above, water can scald. Never test the supply by hand, and leave any adjustment to the heater to a qualified person.
