DV Series
5
It is intended for this manual to be used by qualified service personnel for the primary
purpose of troubleshooting and repair of the Bradford White DV Series water heaters.
The Honeywell Icon Gas Control will display status codes in the event of abnormal
operation. Status codes are listed in the troubleshooting charts beginning on page 6 of
this service manual. The troubleshooting charts on page 6 will also indicate the
probable cause for the status code and direct the service professional to a service
procedure to properly diagnose the abnormal operation.
In some difficult to diagnose conditions, it may be necessary to isolate the heater from
the vent system to determine the problem.
Contact the Bradford White technical support group immediately if diagnosis cannot be
made using the methods described in this service manual.
Tools Required for Service
Manometer:
A liquid “U” tube type or a
digital (magnahelic) type can be
used. This device is used to measure gas and/or air pressure
and vacuum.
Multi-Meter:
A digital type is strongly recommended. This device is used
to measure electrical values. The meter you select must have
the capability to measure volts AC, volts DC, amps,
micro-amps, and ohms.
Electronic Probes:
In some cases, standard multi-meter probes will damage or
simply not be effective to obtain certain voltage and ohm
readings. It will be necessary to have special
electronic “pin”
type multi-meter probes. These probes are available at most
electronic wholesale outlets.
Thermometer: Used to measure water temperature. An accurate
thermometer is recommended.
Water Pressure Gage:
Used to measure water supply pressure. Also used to
determine tank pressure by adapting to the drain valve of the
heater.
Various Hand Tools:
Pipe wrench, channel locks, open end wrenches (3/8”, 7/16”,
1/2”), 12” crescent wrench, allen wrench set, screw drivers
(common & Phillips),
1/4” nut driver, pliers (common & needle
nose), socket set, side cutters, wire cutters, wire strippers,
wire crimpers, torpedo level, small shop vacuum, step ladder,
flashlight, and 5-gallon pail.
