Water Heater Problems: Quick Fixes and When to Call a Pro

If your shower suddenly turns cold or the thermostat keeps tripping, you’re probably dealing with a water heater problem. Most issues are simple enough to diagnose at home, but some need a qualified technician. Here’s a straight‑forward guide to spotting the common culprits, doing basic maintenance, and knowing when it’s time to get professional help.

Why Does My Water Heater Keep Resetting?

A reset button on an electric water heater is there for a reason – it protects the heating element from overheating. If you find yourself pressing it more than once a month, look for these warning signs:

  • Ground‑fault circuit interrupter (GFCI) trips: Loose wiring or a failing element can cause a short.
  • Thermostat set too high: Most homes are fine at 120°F (49°C). Anything above 140°F strains the unit.
  • Scale buildup: Hard water creates a mineral crust that insulates the element, making it work harder and overheat.

Turn off the power, let the tank cool, and check the element for obvious signs of corrosion. If the element looks damaged, replace it – it’s a $30‑$70 part and usually a quick DIY job.

Maintenance: Flushing, Lifespan, and DIY Checks

Regular flushing removes sediment that can turn a perfectly good heater into a ticking time bomb. Most manufacturers recommend flushing once a year, but if you have very hard water, twice a year is safer.

How to flush: Turn off the gas or electricity, attach a garden hose to the drain valve, open the valve, and let the water run until it’s clear. Close the valve, refill the tank, and fire up the heater.

Following a good flush schedule can add 5‑10 years to a tank’s life. Speaking of life, a typical electric water heater lasts 10‑15 years, while a gas model can stretch to 15‑20 years if you keep the flue clean and the burner free of debris.

Two quick DIY checks before you call anyone:

  1. Check the pilot light (gas models): A yellow or flickering flame means the gas valve may be dirty.
  2. Listen for rumbling or popping: Those sounds usually mean sediment is boiling at the bottom of the tank – time to flush.

If you spot any of these signs, a professional repair can save you from a cold shower and a pricey replacement. Our local experts in Bognor Regis can diagnose the issue on the spot and get your hot water back in minutes.

Bottom line: Resetting often, noisy operation, or a drop in water temperature? Start with a quick visual check, flush the tank, and replace any faulty parts you can. When the problem persists, call a qualified technician to avoid further damage and keep your hot water flowing.
