STRANGE SOUNDS

Operational Conditions
SMELLY WATER
In each glssslined water heater there is installed at least one anode
rod (see parts section) for corrosion protection of the tank, Certain water conditions will cause a reaction between this rod
and the water. The most common complaint associated with the
anode rod is one of a "rotten egg smell". This odor is derived from hy&ogen sulfide gas dissolved in the water. The smell is th_ result
of four factors which must all be present for the odor to develop:
a. a concentration of sulfate in the supply water. b. tittle or no dissolved oxygen in the water.
c. a sulfate reducing bacteria within the water heater. (This harmless bacteria is
d. an excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.

SmeUy water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater tank and all hot water fines. Call Maytag Customer Service at
If the smelly water persists after the anode replacement and chlo- rinafion treatment, we can only suggest that continuous chlorina- tion and filtering conditioning equipment be considered to efimi- hate the water problem.
Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.
"AIR" IN HOT WATER FAUCETS
[ | A WARNING |
/HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). /Hydrogen gas is extremely flammable and explo- _sive. To prevent the possibility of injury under these
conditions, we recommend the hot water faucet be _opened for several minutes at the kitchen sink
before any electrical appliances which are connect-
ed to the hot water system are used (such as a dish-
washer or washing machine). If hydrogen gas is pre- sent, there will probably be an unusual sound simi-
lar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.
RUMBLING NOISE
In some water areas, scale or mineral deposits will build up on your heating elements. This buildup will cause a rumbling
noise. Follow "Element Cleaning/Replacement" instructions
to clean and replace the elements.
HIGH TEMPERATURE SHUT OFF SYSTEM
The water heater has a high limit shut offsystem with a reset button located above the upper element.
Follow the resetting instructions which refer to the high limit behind the access panel.
