Step-by-Step DIY Fix Guide
- SAFETY: No immediate safety risk — allow the auto recovery cycle to complete.
- Do not add more detergent or interrupt the cycle.
- Once complete, open the drawer and check for remaining suds.
- Run an empty rinse cycle with no detergent to clear residue.
- Clean the detergent dispenser cup.
- For future cycles, use only automatic dishwasher detergent (not hand wash liquid) in the recommended amount.
If the warning comes back after restart
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- A7 appears on every cycle even with correct automatic dishwasher detergent in the correct amount
What This Error Means
The A7 fault code on your Fisher & Paykel DishDrawer means: The dishwasher has detected excessive foam (suds) and has triggered an automatic recovery cycle to reduce it. This is caused by incorrect detergent use and is user-addressable.
The most common cause is: too much dishwasher detergent used.
This fault is user-addressable. A7 should not require professional service. If it appears consistently with correct detergent, the foam sensor may need inspection.
Most Likely Cause by Symptom
The Fisher & Paykel dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Too much dishwasher detergent used
Check first: SAFETY: No immediate safety risk — allow the auto recovery cycle to complete.
Excess foam or detergent residue may be visible.
Likely cause: Wrong detergent type — hand washing liquid creates excessive foam and must never be used
Check first: Do not add more detergent or interrupt the cycle.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Detergent dispenser clogged with old product that released in excess
Check first: Once complete, open the drawer and check for remaining suds.
Common Causes
