  If your Nyle Water Heater's heat pump isn't running because of electrical problems, there are several things to check: * Ensure the circuit has adequate ampacity, referring to the unit's nameplate for requirements. * Inspect field wiring for short circuits or loose connections and tighten them. * Check for loose wiring within the cabinet and tighten. * Consider replacing the thermostat if it has failed. * Reset the phase monitor if the anti-short cycle timer is defective. * If the compressor has burned out, it will need to be replaced.

  If you find water on the floor around your Nyle Water Heater's heat pump or water tank, here’s what to do: * Check for leaks in tubing, valves, or fittings and repair them. * Ensure the heat pump is level; if not, shim it. * Verify the condensate trap is installed correctly to maintain a water column during operation. * Address drain pan overflow by removing obstructions with a pipe snake or compressed air. * In humid environments, condensation may form on the unit's bottom; cover it with foam insulation.
