Boiler type Magnatherm MGV3500

Error code 164

Cause:

Block intake ON

Solution:

- Check wiring and correct any errors.
- Inspect the Block Intake Switch to make sure it is working correctly.
- Reset and sequence the module.
- During Standby and Purge, measure the voltage across the switch. Supply voltage should be present. If not, the Block Intake Switch is defective and needs replacing.
- If the fault persists, replace the relay module.
