Fisher & Paykel AquaSmart Code 26: detergent valve error

What 26 means

On Fisher & Paykel AquaSmart top-load washers, code 26 reports a detergent valve error. The washer has detected that the valve that lets water flush detergent into the tub is not working as expected. The owner sees 26 on the display, and detergent may stay in the dispenser or arrive in the tub poorly mixed.

Common causes of 26

Detergent valve coil open or damaged
Valve connector not seated on the harness
Water supply to the dispenser restricted
Control board valve driver not responding

✓ One safe check you can try

1. Unplug the washer and wait two minutes. 2. Pull out the detergent dispenser if it is removable, rinse it with warm water and dry it. 3. Check that both water faucets are fully open. 4. Plug in and run a short cycle, watching whether detergent flushes through.

! Why to stop there

The valve sits behind panels that should stay closed for safety
Cleaning the dispenser can help only if the cause is residue
We test before swapping anything and put the price in writing first

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.

2626 questions

Can dried detergent cause code 26?

Residue can slow flow, but the code names the valve itself. Cleaning the dispenser is a reasonable first step, and if 26 still shows afterward the valve or its wiring is the next thing to check.

Is the washer still usable?

You can pour detergent directly into the tub as a short-term workaround. That avoids the valve, but the code usually stays until the valve is repaired.

Does it affect the water fill?

Usually not. The detergent valve is separate from the main hot and cold valves, so water may fill normally while 26 is showing.
