Electric Tankless Water Heater Repair in Mt. Pleasant, SC

Common Electric Tankless Water Heater Problems We Solve

Understanding the specific issues that can affect electric tankless water heaters is crucial for effective repair. Our team is adept at identifying the root cause of these unique electrical and plumbing challenges:

No Hot Water or Lukewarm Water

 This is perhaps the most frustrating issue, as it directly impacts your comfort.

• Causes: For electric tankless units, common culprits include a tripped circuit breaker (often due to the high electrical demand), a faulty heating element, insufficient power supply to the unit, or problems with the flow sensor not detecting water movement correctly.
• Our Solution: Our technicians conduct a thorough electrical inspection, test all heating elements for continuity and resistance, assess the power supply and wiring, and examine the flow sensor to ensure it's functioning optimally. We then repair or replace the necessary components, ensuring your unit receives the correct power and processes water effectively.

Unit Tripping Circuit Breaker Repeatedly

An electric tankless water heater draws significant power, and repeated circuit trips signal an underlying electrical problem.

• Causes: This can be due to an overcurrent caused by a shorted heating element, damaged internal wiring, an overloaded dedicated circuit, or a malfunction within the unit's internal electrical components.
• Our Solution: We perform a comprehensive electrical diagnostic, meticulously inspecting the wiring, connections, and all internal electrical components. We test for shorts and overloads, pinpointing the exact cause of the trips. Repairs range from replacing faulty elements or wiring to addressing internal unit malfunctions to ensure safe and stable operation.

Error Codes Displayed

Many electric tankless units feature digital displays that show error codes, providing clues to internal issues.

• Explanation: Common electric tankless error codes might indicate overheating, a flow sensor error, a heating element failure, or voltage inconsistencies. These codes are invaluable diagnostic tools.
• Our Solution: Our specialists are trained to decode these specific electric tankless error codes. We use advanced diagnostic tools to pinpoint the exact cause of the code, whether it requires a simple reset, calibration, or the repair or replacement of a faulty part, getting to the heart of the problem efficiently.

Inconsistent Water Temperature

When your hot water fluctuates from hot to cold without warning, it disrupts showers and other tasks.

• Causes: This often stems from fluctuating water flow (the unit struggles to maintain consistent temperature with variable flow), mineral buildup on heating elements or sensors (which impedes efficient heat transfer), or a faulty thermostat not accurately regulating temperature.
• Our Solution: We address mineral buildup through professional descaling, calibrate or replace problematic sensors, and inspect or repair the thermostat to ensure stable and precise temperature control.

Leaks

 Any leak from your water heater is a serious concern, regardless of its size.

• Causes: For electric tankless units, leaks typically originate from loose connections at the water inlet or outlet, a damaged pressure relief valve (PRV), or, in rare but serious cases, a cracked heat exchanger.
• Our Solution: Our thorough inspection identifies the exact source of the leak. We tighten loose connections, replace damaged PRVs, and provide expert assessment for significant internal damage, advising on the most cost-effective and safe solution.

Strange Noises (Humming, Sizzling)

Unusual sounds often indicate internal issues that require attention.

• Causes: Humming or sizzling sounds usually point to sediment buildup on the heating elements, causing them to work harder or leading to localized boiling, or they could indicate loose internal connections within the unit.
• Our Solution: We perform professional descaling to remove mineral deposits from heating elements and thoroughly inspect all internal components for any loose parts or connections, ensuring quieter and more efficient operation.

• Typical Repair Ranges:

• Minor electrical issues (e.g., circuit breaker reset, minor wiring fix): $150 - $350 • Heating element replacement: $300 - $600 (includes parts and labor, as multiple elements may need replacement) • Flow sensor replacement: $250 - $450 • Descaling/Flushing: $150 - $300 (often part of preventative maintenance but critical for resolving issues caused by mineral buildup)

Note: These figures are general estimates. The exact cost will depend on the specific electric tankless model, part availability, and the complexity of the repair. A professional diagnosis is essential for an accurate and upfront quote.

Electric Tankless Water Heater Repair vs. Replacement: Making the Right Choice

Deciding whether to repair or replace your electric tankless water heater can be challenging. Our experts provide honest assessments to help you make the most informed and cost-effective decision for your Mt. Pleasant home.

• Factors for Repair: If your electric tankless unit is relatively new (typically under 10–12 years old) and experiencing minor, isolated issues, repair is usually the more economical option. Simple part replacements or descaling can significantly extend its lifespan.
• Factors for Replacement: Consider replacement if your unit is nearing or past its typical lifespan (15+ years), requires frequent and costly repairs, or has suffered extensive damage like a cracked heat exchanger. Upgrading to a newer, more energy-efficient model might also be a wise choice if you're experiencing recurring problems or desire enhanced features.
