Troubleshooting (cont'd)
Operational Conditions
SMELLY WATER | HIGH TEMPERATURE SHUT OFF SYSTEM |
In each glasslined 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 associat- ed with the anode rod is one of a "rotten egg smell". This odor is derived from hydrogen sulfide gas dissolved in the water, The smell is the result of four factors which must all be pres- ent for the odor to develop:
a.a concentration of sulfate in the supply water.
b.little 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.
Smelly 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 lines. Call Maytag Customer Service at
If the smelly water persists after the anode replacement and chlorination treatment, we can only suggest that continuous chlorination and filtering conditioning equipment be consid- ered to eliminate 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
AWARNING
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 present, there will probably be an unusual sound similar 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. j
This water heater is equipped with an automatic gas shut off system. The high temperature shut offls built into the gas control valve. This system shuts off the gas supply to the water heater burners when high water temperatures are pres- ent. It is

NOT ENOUGH OR NO HOT WATER
1.Check the manual gas shut offvalve to be sure it is open.
2.Check the pilot flame. It may have gone out. All models have an opening behind the outer door for viewing the pilot.
3.If the pilot is not lit, foUow the "Lighting" instructions in this manual or located above the gas control valve on the water heater to relight the pilot. If the water was extremely hot and is now cold, the high limit safety temperature shut offmay have put out the burner and pilot. If the high temperature
shut offactivates, the gas control valve must be replaced. Call Maytag Customer Service at

4.The gas control knob must be turned to the "ON" position.
5.The temperature adjustment dial may be set too low. See the "Temperature Regulation" section.
6.The gas company can check the gas input to see if it is correct. An underfired water heater will not heat water as quickly.
7.Look for leaking or open hot water faucets. Make sure all are closed.
8.The cold water inlet temperature may be colder during the winter months. It will take longer to heat the water and seem like less hot water.
