Hi

Please advise on what to do. My geyser is on a timer in the morning and evening. It works independently from our solar power. It refuses to come on or allow us to turn on the geyser. 

What type of timer? Picture perhaps?

Hi

Please advise on what to do. My geyser is on a timer in the morning and evening. It works independently from our solar power. It refuses to come on or allow us to turn on the geyser. 

Do you have a ripple switch that allows the municipality/Eskom to control the geyser? 

If so, the timer must be between the ripple switch and the geyser. 

I'm thinking of a home where I had a timer installed to control the geyser. Then the geyser wouldn't turn on. 

Eventually the electrician figured out what had happened. The timer was before the ripple switch. An 'off' signal had been sent whilst the timer was on and had reached the ripple switch which turned off as it was supposed to. But the timer was off when the 'on' pulse was sent, and that pulse did not reach the ripple switch, which stayed off.

When the timer turned on again, the ripple switch was off, so no power to the geyser. 

We first tested the idea by overriding the timer. The ripple switch came on during that day. 

We then moved the timer so that it was between the ripple switch and the geyser. The problem of the geyser never turning on went away, but this was still not ideal as it was impossible to predict when the City would send pulses to the ripple switch.

Another possibility is that your timer switch is rated for a lower current than the geyser draws. In this case it is probably terminally damaged. Three options (all of which will require a new timer) 

1) get a timer that can handle the load

2) downgrade the geyser element (draws less current, but you will have to run it for longer) 

3) have the timer control a relay which can handle the current the geyser draws.
