Troubleshooting Manual
WARNING
There are a number of live tests that are required when fault finding this product. Extreme care should be used
at all times to avoid contact with energized components inside the product.
You MUST be a qualified service person before proceeding with these test instructions.
Before checking resistance readings, turn off power source to unit and then isolate each item to be checked
from the circuit by unplugging it.
When setting gas pressures on one of these units, please check the complete model number you are trouble-
shooting. Gas pressures and dip switches can vary among models. Always check the rating plate for complete
information and follow directions.
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
E- Series Boiler
If any of the original wire as supplied with the appliance must
be replaced, it must be replaced with type 18 AWG wire or its
equivalent.

The troubleshooting steps for a Rinnai E-Series unit showing no spark after its sequence and gas valve issues with error codes P25, A64, and P19 are:

1. Check if the gas valve is open.
2. Verify there is power to the gas valve.
3. Confirm that the gas valve opens.
4. Ensure the minimum gas pre-pressure during start is at least 7" W.C. (17 mbar).
5. Check for 24 Volts at the gas valve during the ignition block’s open position.
6. Inspect the ionization flow, ionization cable, and O2 setting.
7. The minimum ionization current should be 4 µA.
8. The O2 setting should be at least 4.4% for natural gas (NG) or 4.8% for liquefied petroleum (LP).
9. Inspect wiring and connections to the gas valve.
10. If wiring is good and the problem persists, replace the control unit.
