Immersion Heater Timer

[benni8]

Morning,

I have a flat with an electric immersion water heater.

My timer is a grasslin evo save timer.

For the past 5 years, everything has ran like clockwork. I pull the pins out to indicate the water to be heated from 3am till 6am everyday.

For the past few days I have noticed that it comes on time.. but it doesnt stop/turn off anymore.

I have tried a different finish time today, and it still didnt stop at the end time.

Obviously, i am having to turn off the timer manually at the moment so the water doesnt stay on heating all day.

I take it its time to change? Is this a common problem with these sorts of timers after 5 years of use.

Could be the contacts welding closed so time for a new timer I think. Bit of a pain it lasting only 5 years ( circa 1500 operations )

Easily changed just make sure you isolate the power supply first and follow the instructions shouldnt take you more than 30 mins
