Error codes

If Parameter 46 setting is 12 (IDWH Sensor) the follow-

ing “soft” lockouts could occur:

b_38

alternating with a status code of 9

The IDWH Sensor is not properly connected to

the Prestige low voltage terminal strip. Check

for proper connections and terminations.

b_33

alternating with a status code of 9

The IDWH Sensor is short-circuited. Check if

the DHW is being used and is properly con-

nected to the Prestige low voltage terminals.

Ensure Parameter 35 is correctly set for 12 and

is stored properly.

Once the condition is corrected the errors will automati-

cally reset and the Prestige will return to normal operation.
