Rv Water Heater Repair

Cannons RV Repair provides professional RV Water Heater Repair throughout Vancouver, Washington, Clark County, and Cowlitz County.

We diagnose and repair water heater problems in motorhomes, travel trailers, fifth wheels, toy haulers, truck campers, and other recreational vehicles.

Our family has worked in RV repair since 1997. We handle common water heater problems such as no hot water, ignition failure, electric heating problems, leaks, faulty thermostats, control issues, bad heating elements, burner problems, bypass valve problems, and complete water heater replacement when needed.

If your RV water heater is not working correctly, Cannons RV Repair can diagnose the system and recommend the appropriate repair.

Common RV Water Heater Problems

RV water heaters can fail for many different reasons.

Some problems are electrical. Others are related to propane, ignition, water flow, controls, valves, or internal components.

Common problems we diagnose include:

No hot water
Water only getting lukewarm
Water heater will not ignite
Water heater lights and then shuts off
Electric mode not working
Propane mode not working
Water heater leaking
Fault or warning lights
Heating element failure
Thermostat failure
ECO or high-limit switch problems
Control board problems
Igniter problems
Burner problems
Bypass valve problems
Check valve problems
Pressure relief valve issues

Proper diagnosis is important because several different failures can cause the same symptom.

RV Water Heater Not Heating

If your RV water heater is not producing hot water, the cause may depend on whether the unit operates on propane, electricity, or both.

Possible causes include:

Failed electric heating element
Ignition failure
Thermostat problem
ECO failure
Control board issue
Damaged wiring
Blown fuse
Tripped breaker
Propane supply problem
Gas valve issue
Bypass valve positioned incorrectly
Water flow problem

Rather than replacing parts at random, we test the system to determine where the failure is occurring.

Propane RV Water Heater Repair

Many RV water heaters use propane as either the primary or secondary heat source.

When the propane side stops working correctly, symptoms may include:

Clicking without ignition
No burner flame
Burner lights and shuts off
Repeated ignition attempts
Fault light
Weak burner flame
Delayed ignition

Possible causes can include:

Dirty burner assembly
Igniter problem
Gas valve issue
Control board problem
Propane supply concern
Flame-sensing issue
Wiring problem
Thermostat or ECO failure

Cannons RV Repair can diagnose the propane side of the system and determine which component is causing the problem.

Electric RV Water Heater Repair

Some RV water heaters also operate using 120-volt electric power.

If the propane side works but the electric side does not, the problem may involve:

Failed heating element
Breaker problem
Switch failure
Thermostat issue
Wiring problem
Electrical connection issue
Control board problem
High-limit switch failure

Testing the electric side of the water heater helps prevent unnecessary parts replacement.

RV Water Heater Ignition Problems

Ignition problems are one of the most common reasons an RV water heater will not operate on propane.

The ignition system may be affected by:

Dirty burner components
Improper spark
Damaged igniter
Poor electrical connection
Gas valve problem
Propane supply issue
Flame sensor problem
Faulty control board

If the water heater clicks but does not light, or lights briefly and shuts down, the ignition system should be properly tested.

RV Water Heater Leak Repair

Water around an RV water heater can come from several different locations.

Possible leak points include:

Water line connections
Pressure relief valve
Drain plug
Anode rod opening
Check valve
Bypass valve
Plumbing fittings
Water heater tank

Some leaks can be repaired by replacing a fitting, seal, valve, or other component.

If the tank itself is leaking, replacement is usually required.

Heating Element Replacement

Electric RV water heaters use a heating element to warm the water.

A failed element can cause the electric mode to stop heating while the propane mode continues to work.

Heating element failure may be caused by:

Normal wear
Electrical failure
Mineral buildup
Operating the element without water in the tank
Internal element damage

Cannons RV Repair can test the element and replace it when necessary.

Thermostat and ECO Problems

The thermostat and ECO are important safety and temperature-control components.

A failure can result in:

No hot water
Water not reaching proper temperature
Intermittent heating
Water heater shutting off
Unit failing to operate

These components can be tested to determine whether they are functioning correctly.

Control Board Diagnosis

Many RV water heaters use an electronic control board to manage ignition and operation.

A control board problem can cause symptoms such as:

No ignition
Intermittent operation
Fault lights
Failure to start
Water heater shutting down
No response from the appliance

Because other failures can create similar symptoms, a control board should be diagnosed before it is replaced.

Burner Cleaning and Service

Burner components can collect dust, rust, debris, and insect contamination.

A dirty burner may cause:

Poor ignition
Weak flame
Delayed ignition
Noisy operation
Soot buildup
Reduced heating performance
Water heater shutting down

Cleaning and inspecting the burner assembly can help restore proper operation when contamination is the cause.

Water Heater Bypass Valve Problems

The water heater bypass system is commonly used during RV winterization.

If the valves are positioned incorrectly or a valve has failed, the water heater may appear to have a heating problem even when the heating components are working.

Symptoms may include:

No hot water
Lukewarm water
Reduced hot water flow
Hot and cold water mixing
Water heater not filling correctly

Checking the bypass system can be an important part of diagnosis.

Pressure Relief Valve Problems

The pressure relief valve is a safety component designed to release excessive pressure.

Potential problems include:

Continuous dripping
Heavy leaking
Mineral buildup
Failed valve
Improper pressure

Persistent leaking should be inspected to determine whether the valve or another condition is causing the problem.

RV Water Heater Replacement

Sometimes replacing the water heater is more practical than repairing an older or badly damaged unit.

Replacement may be recommended when:

The tank is leaking
The unit has severe corrosion
Multiple major components have failed
The water heater has repeated failures
Parts are unavailable
Repair costs are approaching replacement cost

Cannons RV Repair can help determine whether repair or replacement makes the most sense.

Tank and Tankless RV Water Heaters

RV manufacturers use several different water heater designs.

Depending on your RV, you may have:

Propane water heater
Electric water heater
Propane/electric combination unit
Traditional tank-style water heater
Tankless RV water heater

Each type has different controls, heating methods, and diagnostic procedures.

RV Water Heater Brands

Many RVs use water heaters from manufacturers such as:

Suburban
Dometic
Atwood
Girard
Furrion
Fogatti
Other RV water heater manufacturers

Repair options depend on the specific model and failure.
