How to fix a Whirlpool 121802 with no hot water?
- M
  Mary WoodsJul 30, 2025
  If your Whirlpool Water Heater isn't producing any hot water, start by checking the electrical switch to ensure it's on. Next, inspect the fuses for any that may have blown or the breaker for any that may have tripped. If the High Temperature Limit Switch is open, reset it, and then investigate the source of the problem to correct it. If the upper thermostat is not functioning, it will need to be replaced.

Why does my Whirlpool 121802 have high operation costs?

  High operation costs for your Whirlpool Water Heater can stem from several issues. Start by checking the thermostat settings; if they are too high, adjust them to the desired level. Improper calibration can also lead to high costs, requiring replacement of the thermostats. Sediment or lime buildup in the tank can reduce efficiency, so drain and flush the tank, and consider water treatment. Other factors include a heater that's too small for the demand (install an adequate heater), incorrect piping connections (correct the piping), leaking faucets (repair the faucets), wasted hot water (advise customer), long runs of exposed piping (insulate the piping), or hot water piping in an exposed wall (insulate the piping).

  If your Whirlpool Water Heater isn't providing enough hot water, several factors could be at play. The thermostats might not be working correctly or may be improperly calibrated, in which case they should be replaced. A non-functioning lower element could also be the cause, requiring replacement. Ensure the thermostats are set to the desired temperature. Sediment or lime buildup in the tank can also reduce hot water availability; draining the tank may help, and consider water treatment. Also check for issues like leaking faucets (repair them), wasted hot water (advise customer), long runs of exposed pipe (insulate the piping), or hot water piping on an outside wall (insulate the piping). If the heater is too small for the demand, install a larger one, and correct any wrong piping connectio...
