Morphy Richards S1 Pro Air Conditioner: Leak Fix & P04 Error Resolution
Verdict: My Morphy Richards S1 Pro air conditioner had a leaking issue regardless of mode and would occasionally display the mysterious P04 error. After some troubleshooting, I found descaling the unit was key to resolving both problems.
Understanding the Leak & P04 Error
The Morphy Richards S1 Pro manual doesn’t mention these issues or provide fixes. Customer service suggested it might be due to scale accumulation and offered a descaling procedure as a solution.
Descaling the Morphy Richards S1 Pro
Here’s how I followed their steps:
- Drained water from the chassis.
- Added citric acid (75g) to the full water tank, then reinstalled it.
- Powered on and started the machine. Once water overflowed, turned off and disconnected power. Waited briefly before draining water again.
- Repeated steps 2-3 about two more times.
Note: Morphy Richards recommends performing this operation in the bathroom to avoid potential floor damage.
Post-Descaling Check & Results
After descaling, I checked if water leakage improved. Happily, both the leak issue and P04 error have been resolved since then!
