The hot water heater, range, and dryer all have 115v to each side of the 240v circuit. The dryer turns, but no heat...no hot water...nothing works on range.
May only be getting 120v from power pole.

Check the voltage at the water heater. Sounds like the element is burnt out and is tripping the breaker.
If it is more then 5 years old I would check.install a new heating element.

I am assuming that this is an electric unit? The heating elements could be bad. I would contact the manufacturer for a service manual for your unit. There you will find instructions on how you might be able to reset the unit if possible. One thing you can try is to shut all power down to the unit and then restart. Also check for any "reset" switches on it as well.

If you don't have current, 0v from terminal to terminal, then you don't have voltage to the elements. Replace the thermostat but check that you have 220v to the thermostat. It is possible that your breakers to the unit are either bad or tripped.

Check to see if diverter valve is in domestic mode or heating mode.
