Fisher & Paykel Built-In Dishwasher Code A70: temperature sensing alarm

What A70 means

On Fisher & Paykel built-in dishwashers from the DW24U and DW60 platform, such as the DW24U6I1 and DW24U2I1, A70 is an alarm error in temperature sensing. The dishwasher could not get a usable temperature reading, so it ended the cycle and reported the alarm. The advice is to switch the machine off and on, and to call for service when the code keeps coming back.

Common causes of A70

Temperature sensing reading outside its normal range
Loose or damaged sensor connection
Control that misreads the sensor signal

✓ One safe check you can try

1. Switch the dishwasher off with the power key and wait one minute. 2. Switch it on and close the door firmly. 3. Run a short rinse cycle to see whether A70 appears again. 4. If it does, leave the dishwasher unused and call us.

! Why to stop there

Telling a sensor problem from a control problem needs measurement, not guesswork.
Opening the lower panel exposes water lines and wiring.
We quote in writing before touching anything, then stand behind the work for 30 days.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

A70A70 questions

How is A70 different from A60?

A60 reports a water temperature error, while A70 is an alarm raised in the temperature sensing itself. Both ask for a power cycle first, but A70 points more at the reading than at the water.

Can I keep washing dishes by hand while waiting?

Yes, and that is the safest choice. Leave the dishwasher switched off until we test it, so a bad reading cannot start a heating stage on its own.

What will a technician check?

We check the sensing circuit and its connections, confirm the reading with proper tools, and explain what needs replacing. You see a written price before work, and our 30-day workmanship warranty applies.
