Here at work and we have a little electric hot water heater. It had been sitting for a while but I just installed it because the old identical one just died. I properly installed this one and it worked great for 4 days. Today it’s having issues. If you let it sit with it’s 2.7 gallon tank. It will heat the water in it from cold to its set temp at 110 in about 1min 15 second. Slow right? I thought so too. How ever I de-energize the unit just a minute ago and see it has 10 ohms of resistance..... Sooooo why? It’s getting 120vac like it should. It has good resistance. The thermostat is saying it needs heat and it is heating just very slowly. This screams needing a new element but am I missing something? Thoughts? The excate model I have is a: Bosch Tronic 3000T - 2.5 model. Thank you for any information on this!!
