Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Count defrost cycles per hour in cold conditions and inspect coil cleanliness.
When to call us
Excessive defrost kills heating capacity — book a service before winter peak load.
Likely causes
What to check
Record the exact error code from the display before resetting — codes are model specific.
When to call us
Send us the code and we arrive with the right part rather than diagnosing twice.
Likely causes
What to check
Clean the strainer, vent the high points and verify pump speed and differential pressure.
When to call us
If flow errors persist after venting, call us — the hydraulic design may need review.
