Maintaining a luxury coach means staying ahead of your heating system’s needs to ensure consistent comfort on the road. At Longship RV, we know the Aqua-Hot system is a powerhouse of efficiency, providing both interior warmth and endless hot water. However, like any diesel or gas burner, it requires precise calibration and regular maintenance to function safely. Recognizing early warning signs can prevent a complete system failure during your next trip.
Signs of a Clogged or Failing Aqua-Hot Burner
Excessive Smoke or Strong Exhaust Odors
Visible smoke coming from your exhaust pipe is a primary indicator that the fuel-to-air ratio is off or the nozzle is partially clogged. While a small puff at startup is normal, continuous clouds or a pungent diesel smell suggest unburned fuel. We recommend immediate inspection to prevent soot buildup from damaging the internal combustion chamber or creating a safety hazard.
Inconsistent Water Temperatures
If your morning shower fluctuates between scalding and freezing, your burner is likely struggling to maintain a consistent flame. This instability often stems from a failing fuel pump or a compromised ignition coil within the unit. We see this frequently when regular annual service is skipped, leading to a system that cycles on and off too rapidly to provide steady heat.
Unusual Noises During Startup
A healthy Aqua-Hot system should engage with a smooth, predictable hum. If you start hearing high-pitched squealing, grinding, or a loud "thumping" sound when the burner tries to ignite, internal components are likely failing. These sounds often point to a worn-out motor or a failing bearing assembly. Addressing these mechanical issues early prevents more expensive and complicated motor replacements down the road.
Frequent Flame Outs or Resetting
Finding yourself constantly resetting the electronic controller is a clear cry for help from your heating system. When the sensors detect an improper flame or a lack of ignition, the system enters a lockout mode for your protection. This behavior is typically caused by a fouled flame sensor or a clogged fuel filter that restricts the necessary flow for a sustained burn.
