Viking Water Heater: Won't Start or Turn On

On gas units, typically a thermocouple or igniter fault; on electric, a tripped reset or failed element. Add a photo of your Viking Water Heater in the box below: the Triage Profile says what it is, how urgent it is, and who to call.

Safe first steps, before the call. Nothing here needs a tool.

  1. If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.

  2. No gas smell? Turn the water heater’s gas control knob to OFF if it’s gas, or switch off its breaker if it’s electric.

  3. Take a photo of the tank, the floor and its label, without opening anything.

Everything else about this problem

Is it an emergency?

Is a Viking water heater that won't start an emergency?

Rarely an emergency. Check its breaker and, on a gas unit, the display or the label by the gas control. Stop and call a pro if it keeps tripping the breaker, smells like burning, or you smell gas.

Symptoms & causes

When a Viking water heater won't start or turn on, common symptoms include no hot water, a completely dark control panel, or a lack of any operational sounds. Root causes often stem from electrical issues like a tripped breaker or faulty thermostat, or for gas models, a pilot light failure or gas supply interruption. Viking units may also enter a safety lockout mode due to sensor errors or power fluctuations, preventing normal operation.

Tools & parts

You will need a multimeter for electrical tests to test voltage and continuity of components. A basic screwdriver set is essential for accessing control panels and thermostats. For gas models, a long lighter or propane torch will be useful for pilot light ignition.

Safety first

Always begin by shutting off the electrical power at the circuit breaker for electric models, or turning off the main gas supply valve for gas models, to prevent electrocution or gas leaks. Be extremely cautious of scalding hot water if the unit has been partially heating, and never attempt to bypass any safety devices. Ensure the work area is well-ventilated, especially when dealing with gas appliances, to avoid carbon monoxide buildup.

When to call a pro

Specific failure modes requiring a professional technician include a faulty gas control valve, which is a complex and dangerous component to replace without specialized training and tools. Issues with the main control board or electronic ignition system on Viking models often require advanced tests and proprietary parts that only certified technicians can properly install. Furthermore, any suspected gas leaks or problems with the pressure relief valve should immediately prompt a call to a qualified professional for safety reasons.

Questions people ask

Why is my Viking water heater not getting power?

First, check your home's electrical breaker for the water heater; it might have tripped due to an overload or short circuit. For electric models, also inspect the red reset button on the upper thermostat, as it often trips due to overheating and needs to be manually pressed.

What if the pilot light won't stay lit on my Viking gas water heater?

A common cause for a pilot light not staying lit is a faulty thermocouple, which senses the pilot flame and signals the gas valve to stay open. Clean or replace the thermocouple, ensuring it is properly positioned in the pilot flame to receive adequate heat.

My Viking electric water heater has power but no hot water. What's wrong?

This often points to a failed heating element or a tripped lower thermostat, even if the upper thermostat is fine. After shutting off power, carefully test both heating elements for continuity with a multimeter and replace any that show no resistance.
