Most tankless problems announce themselves the same way, with a blinking code on the display and a shower that turns cold. Behind that code is a system with very little margin for error. There is no storage tank to fall back on, so the heater has to detect flow, light a burner or power its elements, and raise the water temperature by fifty degrees or more in the few seconds it takes water to cross the heat exchanger. When scale narrows the passages, when the flow sensor stops reading, when the flame rod cannot confirm a flame, or when the vent or gas line cannot keep up, the unit protects itself by shutting down. That is the pattern we see again and again in Westland, MI.
Our approach to tankless repair is simple: measure first, replace second. When we arrive at your Westland 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.
The good news is that most tankless problems are very fixable. A descaling flush clears most mineral buildup, sensors and igniters are replaceable parts, and venting faults usually come down to a blocked intake or a loose joint. We carry common parts for the major brands and service both gas and electric units, so a typical tankless repair is done in one trip. We are also honest about the harder cases: a unit fed by a gas line too small for its full BTU rating will keep throwing codes until the line is upsized, and a heat exchanger damaged by scale may not be worth repairing on an older heater. And if your complaint is the cold-water sandwich, that brief burst of cold between two hot draws, we will tell you whether it is normal for your model or something we can reduce.

Warning Signs to Watch For
A heater that is starting to struggle rarely hides it for long, and the clues are easy to spot once you know them. These are the red flags our technicians see most often before a breakdown:
- A fault code on the front panel and no hot water
- A combustion fan that sounds louder or rougher than normal
- Outlet temperature that surges and sags while water is running
- Repeated ignition attempts, then a shutdown
- Temperature dropping sharply when a second shower or the dishwasher starts
- Leaks under the unit or around its water connections
- Cold slugs in the middle of hot water that last longer than before
- No hot water at a low-flow faucet even though the shower works fine
Act Before It Gets Worse
Tanks rarely fail all at once. They corrode from the inside for months, and the warning signs show up long before the floor gets wet. Don't wait. Get Westland Water Heater on the phone at (734) 280-6297 and we'll get a technician scheduled.

Why This Job Calls for a Pro
Tankless repair is a poor fit for DIY for two reasons: the diagnosis is tricky and the hazards are real. On the diagnostic side, an ignition code might mean a worn igniter, a dirty flame rod, low gas pressure, or a blocked intake, and replacing parts until the code clears adds up fast. On the safety side, a gas unit burns fuel at a very high rate and vents exhaust that contains carbon monoxide, while an electric unit can pull more than 100 amps through multiple 240-volt breakers. Errors with either type can be serious.
A trained technician with the right instruments gets to the answer faster. Ours read the fault history, measure flame signal and igniter resistance, test flow sensor output, and check gas pressure under full load with a manometer, which is the only reliable way to catch a gas line that holds pressure at idle but sags when the burner ramps up. We descale with a circulating pump and the right solution, then flush thoroughly so nothing corrosive is left in your plumbing. Just as important, you get an honest opinion: if the heat exchanger is damaged on an older unit, we will say so before you spend money on a repair.
What to Expect From Our Team
We work through a clear, repeatable process so you always know what's happening and what it will cost. Here's what you can expect when you choose Westland Water Heater:
Diagnose the Error Code
We pull the active error code and the stored fault history, then check every component that code involves: flow sensor, igniter, flame rod, gas pressure, and venting. That way we fix the actual cause, not just the code.
Honest Answers & Upfront Price
You see what failed and hear why, then get 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.
Full Performance Test
We run hot water at several flow rates, confirm the unit lights reliably and holds temperature, and check gas pressure at full fire before we leave.
Tips to Keep Your Water Heater Healthy
A little routine care goes a long way toward keeping a water heater running well past its expected lifespan. Follow these tips from our technicians:
- Write down any error code before resetting the unit, and call if it keeps coming back
- If scale comes back quickly, add a softener or a scale-prevention cartridge on the cold inlet
- Leave the power on in cold weather, since freeze protection only runs when the unit has electricity
- Clean the inlet water filter screen a few times a year so the flow sensor gets full flow
- Have the gas line evaluated whenever you add a range, dryer, or fireplace
- Keep the vent termination and air intake clear of leaves, nests, snow, and lint
- Flush scale out of the heat exchanger annually, and sooner in hard water
Should You DIY or Call a Pro?
Some simple checks are fine to do yourself, but most water heater repairs benefit from professional tools, training, and experience. A side-by-side look:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Diagnosis | Trial and error based on the manual | Fault history and live readings pinpoint it |
| Scale Removal | Vinegar poured in without proper valves | Pump-circulated flush through service valves |
| Combustion Safety | No way to test pressure at full fire | Combustion, venting, and gas supply checked |
| Electrical Work | Exposed wiring and sensitive electronics | Circuits and board checked with proper tools |
| Replacement Parts | Wrong sensor ordered on a guess | Right part, installed once |
| Result | Code returns within weeks | Unit tested at low and high flow |
