Recirculation Pump Repair in Sherwood
Many tankless systems use internal or external recirculation to deliver hot water more quickly. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your routine. A properly tuned system saves both water and gas.
Ignition Failure Repair in Sherwood, AR
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Condensing Tankless Repair in Sherwood, AR
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and confirm proper drainage. PVC venting is also checked for slope and sagging.

Frequently Asked Questions About Tankless Water Heater Repair in Sherwood
The cost of tankless water heater repair in Sherwood varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
Yes, DGR Plumbing stands behind its work. All our tankless water heater repairs come with a satisfaction guarantee and a warranty on both parts and labor. We will provide full warranty details with your repair estimate.
Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent many of these problems.
We service Navien, Rinnai, Noritz, Rheem, Takagi, A.O. Smith, Bosch, Stiebel Eltron and EcoSmart units, among others.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a few years.
Error codes can be triggered by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code corresponds to a specific system malfunction.
Common signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.
Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Sherwood. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to confirm code compliance.
