Tip: Instant Hot Water Dispenser Problems

Hot water dispensers normally keep on working without any sort of routine maintenance.

If you’re having a problem with your unit, please consult the owner’s manual, or hire a service professional to help determine and solve the problem.

Here are problems that may occur with hot water dispensers:

Hot water leaking from the faucet:

A little hot water leaking from the faucet from time to time is normal. Water increases in volume as it heats, so a small amount of water may drip from the faucet to relieve the pressure inside the water tank under the sink.

If the leak is continuous, though, the shut-off valve needs to be repaired. That usually requires the help of a qualified technician.

The water is too hot:

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.

Poor water pressure:

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 obstructed—either a valve isn’t open all the way, or there’s something blocking the tank output or faucet.
