Why does my unit show an error code in my Des Moines home? Error codes often point to ignition faults, flow sensor issues, or hard-water scale in the heat exchanger. We read the code and diagnose the exact cause.
Why does my tankless water run cold suddenly? A cold-water sandwich or sudden cooling can come from scale buildup, a flow problem, or an ignition fault. We test and repair the underlying issue.
Does hard water hurt a unit heater? Yes. Hard Des Moines water scales the heat exchanger, the most common cause of tankless trouble here. Descaling restores performance.
Are your plumbers licensed and insured? Every Lazer plumber is fully licensed and insured, and we complete all work to code.

Most tankless failures; like scale buildup choking the heat exchanger, ignition faults, the error codes that follow. trace back to one cause in a city with water this hard: minerals. Our licensed technicians clear them and restore steady hot water, backed by our 100% Satisfaction Guarantee. Staying ahead of that buildup is exactly what a routine tankless tune-up does, which is why it’s one of the most popular Des Moines water heater services we provide.

A tankless water heater acting up tends to show it a few different ways:
• Inconsistent or fluctuating hot water
• An error code on the display
• A drop in flow rate
• Hard-water scale warnings
Because scale drives most tankless faults in hard-water areas, early service keeps it running. Call (515) 212-6042 for your free repair estimate.

Common Tankless Problems We Repair

Tankless units develop a few recurring faults, scale chief among them. These are the three our plumbers repair most across the metro:

Mineral scale from hard Des Moines water coats the heat exchanger, cutting efficiency and triggering error codes. We descale the unit to restore full performance. Regular descaling prevents it returning. Because Des Moines water is so hard, scale is by far the most common reason a local tankless unit throws a fault. We descale as part of the repair when scale is the cause, so the fix lasts rather than recurring.

A unit that will not ignite or keeps shutting down often has an ignition, gas, or flame-sensing fault. We diagnose and repair it so the heater fires reliably. We also check the gas supply and venting as part of the work. We confirm the gas pressure and venting too, since both can mimic an ignition fault. We verify the fix under real flow so you know the hot water will hold during a long shower.

Flow sensor and temperature problems cause cold spells and fluctuating water. We test the sensors and flow path and repair the fault so hot water stays steady. Pinpointing the exact sensor avoids replacing parts unnecessarily. Restoring steady, endless hot water is the whole reason you chose tankless, and we make sure it delivers.
