Why is my Whirlpool Energy Smart 188410 not producing enough hot water?
- K
  Kelly NewtonJul 30, 2025
  Several factors could be responsible for insufficient hot water. It could be due to a defective dip tube, or the temperature might be set too low. Sediment or lime accumulation in the tank can also cause this issue, as well as wrong piping connections. Check for leaking faucets and plumbing, and consider whether the heater is adequately sized for your needs. Also, wasted hot water, and long runs of exposed or uninsulated pipe can contribute.

  To reduce high operation costs, first ensure the temperature isn't set too high, consider using the Energy Smart® Mode. Draining and flushing the tank to remove sediment or lime is also important. Other factors include: repairing leaking faucets and plumbing, reducing wasted hot water, and insulating exposed piping. If the elements are covered with sediment or lime, consider replacing them. Finally, ensure you have an adequately sized heater for your needs.
