Water heater frequently shuts off when other taps or appliances are used, causing temperature drops.

Comfort issue: This is usually a hydraulic problem rather than an internal heater fault.

• 1. Check inlet valves:
  • Ensure the cold water isolation valve to the heater is fully open.
• 2. Clean inlet filter: Remove and clean the inlet filter screen.
• 3. Avoid simultaneous high demand:
  • Limit use of other large water consumers (washing machine, garden hose) while showering.
• 4. Consult a plumber: If pressure drops significantly when other fixtures run, upgrading the supply line or installing a pressure‑balancing system may be necessary.
