During Heating Non Fatal During heating,
water detected at
high probe for more
than 10 seconds. Clean all probes and
drains.
02
Probe Error -
Start up Fatal During startup, low,
or high, or both
probes are not
detected (Open) Clean all probes and
drains.
03
Probe Error (Out
Of Sequence)
- Start up &
Shutdown Non
Fatal or
Warning Probes are out of
proper sequence
during Start up or
Shutdown Clean all probes and
drains.
04 Overflow Error Fatal Overflow probe is
detected for more
than 10 seconds. Clean all probes and
drains.
05
High Probe Error -
No Call For Water
-During Heating Fatal During heating, high
probe is closed and
unit has not called
for water within 20
minutes. Clean all probes and
drains.
06 Probe Error -
Hot Fill Time
Exceeded -During
Heating Fatal During heating or
shutdown, probes
not detected to stop
water fill within 5
mins of the unit
calling for water.” Clean all probes and
drains.
07 High Probe Error -
Delime Mode Fatal During delime
mode, high probe
not detected to stop
water fill within 5
mins of the unit
calling for water. Clean all probes and
drains.
08 Communication
Failure Fatal IO Board to
Controller Board
Communication
has been disrupted
. Error can only be
cleared by cycling
main power switch. Make sure
communication
harness connections
are secure; Replace
communication
09 Control Voltage
Error Fatal 24 volt DC supply
voltage is out of
range
10 Drain Time
Exceeded Fatal During Startup,
Shutdown or Delime
mode, drain time
on the low or high
probe exceeds 10
minutes. Clean all probes and
drains.
11 Control
Temperature
Exceeded Fatal I/O board has
exceed preset
temperature of
185°F/85°C Ensure the unit has
proper clearances;
Ensure the cooling
fan is operational or
not blocked.
12 Low Voltage Fatal Transformer output
voltage is between
19 and 20.5 V Ensure incoming
voltage supply is
within 10% rating
on data plate.
13 Low Voltage Fatal Transformer output
voltage is below 19V Ensure incoming
voltage supply is
within 10% rating
on data plate.

Description
Corrective Action
14 High Voltage Fatal Transformer output
voltage is above
31 V Ensure incoming
voltage supply is
within 10% rating
on data plate.
15
Fill Valve Failure Fatal Fill Valve / Fill Valve
circuit current is
out of range for
the current state of
the valve. Standard
operating current is
between 150mA to
500mA. Check for proper
voltage going to
fill valve from I/O
board; Ensure fill
valve is operation
and current value is
within range.
16 Drain Valve
Failure Fatal Drain Valve / Drain
Valve circuit current
is out of range for
the current state of
the valve. Standard
operating current
is between 250mA
and 900mA. Check for proper
voltage going to
drain valve from I/O
board; Ensure drain
valve is operation
and current value is
within range.
17
Condensate Valve
Failure Fatal Condensate Valve /
Condensate Valve
circuit is out of
range for the current
state of the valve.
Standard operating
current is between
150mA and
500mA. Check for proper
voltage going to
condensate valve
from I/O board;
Ensure condensate
valve is operation
and current value is
within range.
18 Cooling Fan
Failure Fatal Cooling Fan /
Cooling Fan circuit
is out of range for
the current state of
the valve. Standard
operating current is
between 50mA and
260mA. Check for proper
voltage going to
the cooling fan
from I/O board;
Ensure cooling fan
is operational and
current value is
within range.
19
Cooling Fan
Failure Fatal Drain Tstat Triggered
due to excess heat
(due to Muffin Fan
Failure ) Ensure drain
thermostat is
closed. Allow drain
box to cool or
manually fill cavity
with cool water.
Check continuity on
harness between I/O
board connector and
terminals at drain
thermostat.
20 Maximum
Temperature
Exceeded Fatal Hi limit Tstat
Triggered due to
excess heat Ensure hi limit
thermostat is
closed. Allow
cavity to cool or
manually fill cavity
with cool water.
Check continuity on
harness between I/O
board connector and
terminals at hi limit
thermostat.
