Weil-McLain C-1013 Troubleshooting Manual page 11

Is the source of water from the tank?
- Check for possible overhead pipes leaking onto the tank. (Non-Warranty)
Check all connections – boiler connections, air vent...
- Check the connections to the water heater. Are they loose? A build-up of corrosion around
joints is a sure sign of a leak. (Non-Warranty)
- Check the seal around the air vent and drywell for leaks. Remove the drywell and check
the O-ring gasket (if applicable) beneath it. (Non-Warranty) If they are leaking and it is
not related to an installation error or system problem—*reason code 058.
- Remove the thermostat sensing bulb from the drywell. If the bulb wet or is water visible at
the top of the drywell?—*reason code 059.
Action Item:
- To replace the drywell use the Replacement Kit. (See chart on Page 15, 17, 19 or 21)
- Apply sealant (i.e. Leaklok or Loctite) completely around threads in all applications.
* This may be a manufacturing defect. Please initiate a warranty claim with Weil-McLain
