This is my first post. Please help. Dad was an electrician but didn't teach me all he knew! A few months ago old mechanical timer on immersion heater stopped working and burned the cable at the immersion terminal. I replaced timer with a LAP digital weekly immersion timer and replaced the heat resistant cable between timer and immersion. Worked fine until two days ago. Water stone cold. Have power to timer and readout says it is on when timer should be. Have continuity at the immersion heater. Have no power across N and L output side of timer when timer says it is on. Does this mean the timer is faulty or could it be the cable or immersion or immersion thermostat?
