Common Warning Signs
Homeowners in Avondale and the West Valley often notice these symptoms before a full failure:
- Hot water goes cold mid-shower
- Error codes on the tankless unit's display
- Fluctuating water temperature
- The unit fires but doesn't deliver hot water
- It's been over a year since the last descale
When Is It Urgent?
A tankless unit showing an error code or leaking should be checked before continued use. If you smell gas near the unit, leave the area and call.
What to Do While Waiting for Service:
- Note any error code displayed on the unit
- Avoid repeatedly resetting the unit if it keeps faulting
What to Avoid:
- • Don't use standard drain cleaner through a tankless system
- • Don't ignore annual descaling — scale buildup is the top cause of tankless failure
