Common Issues and Troubleshooting
Addressing common problems with your Reliance 606 is often straightforward․ Pilot light issues, frequently caused by condensation, and occasional leaks are typical concerns requiring prompt attention․
Pilot Light Problems: Initial Diagnosis

When your Reliance 606 pilot light repeatedly extinguishes, a systematic approach to diagnosis is crucial․ Begin by carefully observing the flame’s behavior immediately after ignition․ Does it burn with a strong, blue flame, or is it weak and yellow? A weak flame suggests insufficient gas supply or a dirty pilot orifice․

Next, check for any visible obstructions around the pilot assembly․ Dust, debris, or spiderwebs can disrupt the flame pattern․ Gently clean the area with a soft brush or vacuum․ If the pilot light still won’t stay lit, consider the possibility of condensation; As noted in user reports, cold water entering the system can cause water to drip onto the burner, extinguishing the pilot after the heating cycle ends․

Allow sufficient time (an hour or more) for the unit to dry out before attempting to relight․ Before proceeding with more complex troubleshooting, ensure the gas supply is fully open and that the thermocouple is properly positioned within the flame․ A faulty thermocouple is a common cause of pilot light failures․
Pilot Light Won’t Stay Lit: Condensation Issues
A frequent cause of pilot light failure in the Reliance 606 water heater is condensation, particularly when heating cold water․ As reported by users on DIY forums, water can drip onto the burner immediately after relighting, quickly extinguishing the pilot flame once the burner shuts off․ This cycle repeats, making it difficult to maintain a consistent pilot․
This condensation occurs because the temperature difference between the cold incoming water and the hot flue gases creates moisture․ This moisture then collects and drips, disrupting the pilot․ The recommended solution is patience; allow the unit several hours to thoroughly dry out before attempting to relight․
Avoid repeated attempts to ignite the pilot during this period, as this can exacerbate the problem․ If the issue persists even after a prolonged drying period, investigate other potential causes, such as a faulty thermocouple or a blocked vent․ Remember to always prioritize safety and consult a qualified technician if you are unsure about any aspect of the repair․
Pilot Light Repeatedly Extinguishing: Cleaning the Air Vent
If your Reliance 606 water heater’s pilot light repeatedly extinguishes after initially lighting, a clogged air vent is a likely culprit․ Experienced users on appliance repair forums, like Appliantology․org, have reported success resolving this issue through simple cleaning․ The air vent provides essential airflow for stable combustion․
Dust, debris, or even spiderwebs can obstruct this vent, disrupting the gas flow and causing the pilot to flicker and eventually go out․ Locate the air vent – typically a small opening near the pilot assembly – and carefully clean it using a small brush, compressed air, or a thin wire․
Ensure you turn off the gas supply before attempting any cleaning․ After cleaning, relight the pilot and observe its stability․ If the problem persists, consider other potential causes, such as a faulty thermocouple or gas valve․ Regular inspection and cleaning of the air vent can prevent this recurring issue․

Leakage Checks and Prevention
Regularly inspect your Reliance 606 for leaks, focusing on connections and the tank itself․ Many suspected tank leaks originate elsewhere; prompt attention prevents damage․
Identifying Potential Leakage Points
When investigating a water leak around your Reliance 606 water heater, a systematic approach is crucial․ Begin by carefully examining all pipe connections – both the hot and cold water inlets and the gas line․ Look for drips or signs of corrosion around these fittings․ The Temperature and Pressure Relief (TPR) valve is another common source of leakage; a small amount of discharge here can be normal, but consistent dripping indicates a problem․
Inspect the drain valve at the bottom of the tank for any signs of leakage․ Also, check around the burner compartment and the flue pipe connection․ Remember that what appears to be a tank leak might actually be condensation, especially during initial operation or in humid environments․ Carefully differentiate between water dripping from condensation and actual leakage from the tank itself․ A thorough visual inspection, combined with feeling for dampness, will help pinpoint the source of the problem․ If you are unsure, contacting a qualified service agency is always recommended․
Distinguishing Tank Leaks from Other Water Sources
Accurately identifying the source of water near your Reliance 606 is vital․ Many suspected tank leaks are, in fact, originating from elsewhere․ Condensation, particularly when heating cold water, can mimic a tank leak, dripping from connections or the burner area․ Carefully observe if the dripping stops after the water heater completes a heating cycle – condensation typically ceases then․
Check the TPR valve discharge pipe for leaks or drips; a small release is normal, but continuous flow indicates an issue․ Examine the drain valve at the tank’s base, as well as all pipe connections for corrosion or loose fittings․ Wipe all areas dry and monitor closely to pinpoint the exact source․ If the water appears rusty, it’s more likely from the tank itself․ If it’s clear, suspect condensation or a plumbing connection․ If uncertainty persists, immediately contact a qualified service agency for a professional assessment to avoid potential hazards․
