Tankless units are clever machines, and that is both their strength and their weak spot. Instead of keeping forty or fifty gallons hot around the clock, a tankless heater springs into action only when water starts moving: a flow sensor detects demand, the control board fires the burner or elements, and water is heated on its way through the heat exchanger. Every step is watched by a sensor, and if any reading drifts outside its expected range, the board shuts the heater off and displays a code. For Murray, UT homeowners, that usually traces back to a short list of causes: scale building up inside the heat exchanger, a sticking or dirty flow sensor, an ignition problem at the igniter or flame rod, or a venting or gas supply issue the unit reads as unsafe.
Our approach to tankless repair is simple: measure first, replace second. When we arrive at your Murray home, we record the active code and the unit's fault history, then work through the systems behind it. Flow sensors are checked with water running to confirm they report demand correctly. Flame rods and igniters are tested electrically. Gas pressure is read at the inlet with the burner at maximum, because a line that holds steady at idle can sag badly under full load. The vent and air intake are inspected end to end, and the heat exchanger is judged by the temperature rise it achieves at a known flow. Only then do we recommend a fix, and we can show you exactly why.
After the fault is pinned down, most repairs are finished in a single visit. We descale heat exchangers with a pump and descaling solution circulated through the service valves, replace worn flow sensors, igniters, flame rods, thermistors, and combustion fans, clean inlet filter screens, and correct venting problems that trip pressure switches. When the real issue is a gas line sized for the old tank heater, we tell you plainly and quote the correct pipe run, because no amount of part swapping will fix a unit that is starved for fuel. If you are fighting a cold-water sandwich, we explain whether it is normal behavior for your model or a sign of a setting, fixture, or recirculation problem we can correct.

Symptoms That Mean It's Time to Call
Water heaters usually give plenty of warning before they fail, as long as you know what to look and listen for. If any of the following sound familiar, it's worth having the unit checked:
- Repeated ignition attempts, then a shutdown
- Longer bursts of cold water between hot draws than you used to get
- An error code flashing on the unit's display
- Hot water that cannot keep up with more than one fixture
- Small draws, like a bathroom sink, that never trigger the heater
- Water dripping from the cabinet or the condensate line
- Outlet temperature that surges and sags while water is running
- New whistling, roaring, or rumbling from the unit
A Slow Leak Never Stays Slow
Most water heater failures start small: a popping sound from sediment, a damp spot under the drain valve, or a shower that goes lukewarm a few minutes sooner each week. At the first hint of a problem, reach out to Murray Water Heater at (801) 998-0110 and we'll take a look.

Why Professional Tankless Water Heater Repair Matters
Consider the risks first. A gas-fired tankless heater can burn nearly 200,000 BTU per hour at full fire, and its vent is the only thing carrying carbon monoxide out of the house; a joint that pulls loose or an intake that gets blocked changes that in a hurry. Electric tankless models are serious electrical loads, frequently more than 100 amps spread over several 240-volt circuits. Then there is the diagnostic puzzle. Error codes point to a system, not a part, so a flow sensor fault, a scaled heat exchanger, and a bad thermistor can look nearly identical on the display, and guessing gets expensive.
What you get from a professional is certainty. Instead of swapping parts, our technicians confirm the fault with a meter, a manometer, and temperature readings, so the fix is aimed at the actual cause. Descaling is done with a pump and service valves, not by pouring vinegar into an inlet and hoping. Gas pressure is checked with the burner at full output, vent runs are inspected against the manufacturer's length and clearance limits, and the unit is tested at low and high flow before we leave. Proper service also keeps you in line with the manufacturer's warranty terms, many of which expect qualified service and regular descaling.
From Your Call to Hot Water
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's what you can expect when you choose Murray Water Heater:
Read the Unit First
Codes get us started; measurements finish the job. Flow sensor output, flame signal, igniter resistance, inlet gas pressure, and vent condition all get checked before any part comes out of the box.
Plain Findings & Firm Quote
We show you the failed part, explain the cause, and give you a firm price before work begins. If scale has cracked the heat exchanger or the unit is near the end of its life, we say so plainly.
Repair & Descaling
We carry the parts that fail most on tankless units, so flow sensors, igniters, flame rods, and thermistors are usually replaced on the spot, and a descaling flush takes about an hour.
Tested Under Load
We never assume a fix worked. We test the unit at low flow and at full demand, confirm a steady outlet temperature, and verify that the code is cleared and stays cleared.

Get Help: (801) 998-0110How to Prevent Water Heater Problems
A little routine care goes a long way toward keeping a water heater running well past its expected lifespan. Start with these practical measures our team relies on:
- Leave the power on in cold weather, since freeze protection only runs when the unit has electricity
- Get the supply line checked before adding gas appliances, which can starve a tankless unit
- Flush scale out of the heat exchanger annually, and sooner in hard water
- Keep the vent termination and air intake clear of leaves, nests, snow, and lint
- Rinse the small filter screen on the cold inlet every few months
- Do not keep resetting a recurring code; note it and have it checked
- Consider a water softener or scale-reduction filter ahead of the heater if scale keeps returning
DIY vs. Professional Tankless Water Heater Repair
Some simple checks are fine to do yourself, but most water heater repairs benefit from professional tools, training, and experience. Here's a comparison:
| Consideration | DIY Attempt | Hiring a Pro |
|---|---|---|
| Reading the Code | Swap parts until the code clears | Code confirmed by component testing |
| Scale Removal | Partial flush that leaves scale behind | Full descale, then a thorough rinse |
| Combustion Safety | Venting and gas supply problems missed | Combustion, venting, and gas supply checked |
| Board & Wiring | Live wiring inside the cabinet | Wiring and connectors tested safely |
| Replacement Parts | Parts bought before the fault is known | Right part, installed once |
| Outcome | Symptom patched, cause remains | Lasting repair, confirmed by testing |
