Common Problems and solutions
Instant Water Heater
1. Power keeps tripping: Often water leakage into heater or worn heating elements. 
2. No hot water: Burnt-out element, faulty thermostat, or wiring issue. 
3. Leaks: Burnt-out element, faulty thermostat, or wiring issue. 
4. Sudden cold showers: Thermostat wear causing unstable heating. 
Storage Water Heater
1. Trips whole house: Leakage from element or wiring.
2. Tank leaking: Failed gasket, corroded tank, or worn sacrificial anode rod.
3. Water not hot enough: Aging heating element or thermostat losing capacity. 
4. Rusty or brown water: Enamel lining inside tank broken.
When to Replace:
• Age: Replace after 5–6 years (instant) or 8–10 years (storage). 
• Leaks/Corrosion Cannot be repaired safely.
• Frequent Repairs: More costly than a new unit. 
• Out of Warranty Ariston (5 yrs element, 1 yr parts), Rheem (6 yrs element, 2 yrs parts). Best to replace.
