B Double check all wire connections 

made under section 4.2 of the 
remote control manual. Pay close 
attention to the wire connecting the 
remote's PCB to the heater's main 
PCB.

B Verify the water heater's ON/OFF 

switch is turned to the ON (I) 
position. If the water heater's display 
is still blank, verify the heater is 
plugged into a live 120VAC/ 60Htz 
properly grounded outlet.

B Verify there is proper voltage to the 

water heater (120VAC/60Htz).

B Verify the remote is within the 

maximum distance from the water 
heater of 98 feet.

B Ensure that no other device in the 

area, such as a cordless phone, is 
operating on a frequency similar to 
the remote (915 MHz) and causing 
interference

B

Error codes cannot be reset by

using the remote. All errors must be

cleared by using the reset button

 on the water heater's main

control panel

• If an error code is generated immedi-

ately after the installation of the 
remote control transceiver PCB, 
ensure two large electrical connec-
tors (Fig. 4) on the main PCB are 
properly seated.

• Error code may not be resettable. 

Consult water heater's installation 
manual or www.boschhotwater for 
further troubleshooting on error 
codes.

Large amounts of metal 
or concrete in the 
structure may have a 
blocking effect on the 
remote's signal. This 
may alter the maximum 
distance allowable from 
the water heater.

B Move within direct 

line of sight of the 
water heater to see if 
signal will reconnect.
