Hot water dispensers normally keep on working without any sort of routine maintenance.
There are, however, occasional hot water dispenser problems that may occur:
Problem: Hot water is leaking from the faucet.
If the leak is continuous, though, the shut-off valve needs to be repaired. That usually requires the help of a qualified technician.

Problem: The water is too hot.
Solution: The temperature control on residential hot water dispensers is normally factory-set. But, you can usually set it to a different temperature. Consult your owner's manual to learn how to set yours.
To avoid scalding, don't set the temperature above 120 degrees Fahrenheit.
Problem: Poor water pressure.
Solution: The amount of water coming from the hot water dispenser is primarily determined by the amount of water entering the tank below. If the water flow is unusually slow, though, the incoming water may be obstructedeither a valve isn't open all the way, or there's something blocking the tank output or faucet.
