Problems We Solve
Common Tankless Water Heater Repair Problems We Fix
Here are the issues our team commonly finds and resolves during tankless water heater repair calls across Central Florida.
No Hot Water at All
If your unit fires but produces cold water — or won't ignite at all — the cause is often a failed igniter, tripped flow sensor, or gas supply issue. Our technicians isolate the fault quickly and restore full heat output.
Error Codes on the Display
Modern tankless heaters flash fault codes when something goes wrong. We carry manufacturer diagnostic tools and service literature for all major brands, so we decode the error correctly and fix the right thing the first time.
Inconsistent Water Temperature
Water that swings between hot and cold — or never quite reaches the set temperature — often points to a failing flow sensor, scale buildup in the heat exchanger, or a faulty thermistor. We identify and correct the root cause.
Mineral Scale Buildup
Orlando's hard water accelerates scale deposits inside the heat exchanger, reducing efficiency and triggering overheating shutdowns. We descale and flush the system to restore normal operation and protect the unit long-term.
Unit Shuts Off During Use
A tankless heater that cuts out mid-shower is often overheating due to restricted water flow, a dirty inlet filter, or a blocked exhaust vent. We inspect the full system and restore reliable, uninterrupted operation.
When to Call
Signs Your Water Heater Needs Professional Attention
If you notice any of these warning signs, schedule tankless water heater repair before the problem becomes more disruptive or expensive.
No Hot Water at Home
If you're turning on the hot tap and getting nothing but cold water, your tankless unit may have shut down due to a fault. Don't wait — call us and we'll get a technician out fast.
Error Code Won't Clear
A persistent error code that reappears after a reset is your unit telling you something is genuinely wrong. Ignoring it risks further damage and a more costly repair down the road.
Hot Water Takes Much Longer
If you're waiting significantly longer than usual for hot water to arrive, your unit may be struggling with scale buildup or a failing component that's reducing its heating capacity.
Unusual Noises During Operation
Popping, rumbling, or whining sounds from your unit often indicate scale buildup on the heat exchanger or a worn component under stress. Early attention prevents a minor issue from becoming a major repair.
Water Temperature Is Unpredictable
If your shower swings between scalding and cold without any changes on your end, the unit's flow sensor or thermistor is likely failing. A diagnostic visit will confirm what's wrong and what it will take to fix it.

FAQs
Tankless Water Heater Repair FAQs
How much does tankless water heater repair cost in Orlando?
Repair costs vary depending on the fault — a simple sensor replacement is much less than a heat exchanger issue. We provide a firm price after diagnosing the unit, before any work begins, so you’re never caught off guard.
Can you repair all brands of tankless water heaters?
Yes — our technicians are experienced with all major brands including Rinnai, Navien, Noritz, Rheem, Bradford White, and Bosch. We carry manufacturer diagnostic tools and service parts for the most common models.
My tankless heater is showing an error code. What should I do?
Note the code and call us — don’t keep resetting it, as repeated resets without fixing the underlying fault can cause additional damage. We’ll decode the error and get a technician out to correct it properly.
How long does a tankless water heater repair take?
Most repairs are completed in a single visit, typically one to two hours. More complex issues such as heat exchanger replacement may take longer, and we’ll always let you know upfront what to expect.
Is it worth repairing a tankless water heater, or should I replace it?
In most cases, repair is the right call — tankless units are built to last 20 years or more with proper maintenance. After diagnosing your unit, we’ll give you an honest assessment so you can make the best decision for your home.
Why does my tankless water heater keep shutting off?
Intermittent shutdowns are usually caused by overheating — often triggered by scale buildup in the heat exchanger, a clogged inlet filter, or restricted exhaust venting. A diagnostic visit identifies the exact cause and prevents repeat shutdowns.
Do you offer emergency tankless water heater repair in Orlando?
Yes — Lapin Services is available 24 hours a day, 7 days a week, including weekends and holidays. Call (407) 326-3367 any time and we’ll get a technician to you as quickly as possible.
How can I prevent tankless water heater problems in the future?
Annual maintenance — including a descaling flush — is the single best way to keep your unit running reliably, especially in Orlando where hard water accelerates scale buildup. Ask us about a maintenance plan when we’re on-site.
