Water Heater Tripping Breaker

The closer you are to your water heater, the more likely you will notice when something goes wrong. If your water heater trips a breaker, it’s time to investigate what happened and how to avoid it.

To avoid a tripping breaker, you need to check the temperature setting on your water heater to make sure it’s set to a safe level. Also, check the thermostat and the element of your water heater. You should also look at any wiring or connections that may have been made to hook up new appliances, such as an electric dryer or washing machine.

Suppose there are any problems with these components. In that case, they could cause an electrical short in the system which could lead directly back up into your home’s main breaker box and trip their breakers—causing them all over again when they reset themselves after being tripped once more!

Causes Of Water Heater Tripping

  • Loose wire:  A loose wire is the most common cause of a water heater tripping breaker. To check this, turn off your breaker and remove the cover of your water heater. If you find any wires that appear loose or disconnected from their connections, use a screwdriver to tighten them back.
  • High resistance in the element or thermostat:  If you notice high resistance when turning on or off your heater after replacing it with new parts (like an element), this could be the issue. You can test this by removing one terminal at either end of each wire coming into contact with the element and measuring how much voltage is passing through them before making contact again with each terminal being tested individually; if there isn’t enough voltage flowing through each individual connection point then there may be something blocking its path due to corrosion inside one particular part—and therefore causing problems like what happened here!

Loose Wire:

  • Check for loose wires. Loose wires can cause a tripping breaker to trip, even if there is nothing wrong with the circuit breaker itself. Check your circuit breaker and all of its connections to see if they’re tight and secure, then check the thermostat’s connections. If you have any doubt about whether or not a wire is properly connected at any point in its journey, ask someone who knows what they’re doing (like an electrician) for help!
  • Check for loose wire connections at the element or circuit breaker itself that may be causing trouble here.

High Resistance In The Element or Thermostat:

  • Check for high resistance in the element or thermostat.
  • Replace any defective parts.
  • Clean the element (and replace if necessary).
  • Replace the thermostat.
  • Check for loose wiring and make sure it’s not twisted and damaged by corrosion or wear over time, which could cause a short circuit and trip breaker #4 on your water heater; this is usually located near an electrical terminal block near where it connects to your home’s main power line wires, but there may be others as well depending on how far from that you have mounted yours in relation to other appliances like dishwashers/dryers,, so check there too!


To determine if your water heater is contaminated, turn off the power at the breaker box. Then check to see if there’s a pool of water in or around your water heater. If so, you’ve probably got contamination and need to clean up the area where it leaked before dealing with this problem further. If not, check for rust on any metal parts of your system—this could be causing an issue with operation as well as causing corrosion that leads to a trip through circuit breakers when they’re used too much.

What Would You Need?

While fixing up the water heater, you may require one or more of the following items:

  • Discharge pipe
  • Water and gas piping
  • Fittings
  • Solder
  • Pipe thread compound
  • Pressure relief valve
  • Venting pipe and connectors

Solutions For Water Heater Tripping

  • Tighten all electrical connections (ensure you turn off the water heater’s power at the circuit breaker).
  • Drain, clean and flush the
  • Check for leaks.
  • Check for sediment build up in the bottom of the tank.
  • Replace the thermostat or heating element

 1. Tighten All Electrical Connections (Ensure You Turn Off The Power To The Water Heater At The Circuit Breaker):

  • Turn off the power at the
  • Tighten all electrical connections (ensure you turn off power of water heater at circuit breaker).
  • If there are no loose connections, then check the thermostat.

 2. Drain, Clean And Flush The Tank:

To fix a water heater tripping breaker, you’ll need to drain, clean, and flush your traditional tank. This can be done by turning off the power to your home or business and then turning on an outside floodlight (or two) so that light shines directly into the bottom of the tank.


The most common cause of tripping is a loose connection in the electrical circuit. If this is not the case, then consider replacing your water heater.
