F7Warning
Fisher & Paykel Dishwasher F7 Error Code
Water level sensor (pressure switch) indicates abnormal water level – too high or too low.
Common causes
- Overfilling due to faulty inlet valve
- Underfilling due to restrictions
- Faulty pressure switch or air tube blockage
How to fix it
- Check for water in the bottom of tub (should be a few cups, not deep)
- Inspect air tube from sump to pressure switch for blockages
⚠ When to call a pro: If water level is clearly wrong and air tube is clear, pressure switch or valve likely defective
