Gas water heater computer board adjustment troubles many people. This article is written by PHP editor Baicao to provide you with an in-depth analysis of this problem. This article will introduce in detail the adjustment steps of the Rinnai gas water heater computer board, including key operations such as entering debugging mode, adjusting parameters, and saving modifications. If you are troubled by water heater adjustment problems, you may wish to continue reading this article to get detailed guidance and easily solve the problem.
1: Adjust the winter setting to the spring and summer setting, adjust the water temperature to the highest level, and adjust the firepower to the minimum. If the water is too cold, don't touch anything else, just adjust the firepower to the highest level. This saves gas and water, and is easy to start when the floor is high.
2: When winter comes, you can switch from winter to summer. Remember, try not to adjust the water temperature and keep it at the highest temperature all year round. This saves water and gas. Just slowly adjust the heat. Friendly reminder: Adjust any switch gently. If you really need to adjust the water temperature frequently, do it slowly. If the water switch often stops moving and is difficult to adjust, you can remove the twist and use pliers to adjust it. However, it is best not to touch the water temperature at all times and just adjust it to the highest value.
Inspection method for Rinnai water heater display 71:
1. Check whether the switch valve on the gas pipeline is fully open;
2. Check whether the gas is used up.
3. Check the gas balance of the gas meter or whether the gas meter battery has electricity,
4. Check whether the gas is used up or whether the bottle pressure reducing valve is damaged.
5. Check if there is air in the pipe. You can repeat the ignition at an interval of about ten seconds to expel the air in the pipe.
Solutions to Rinnai water heater displaying 71:
1. Check whether the exhaust gas can be discharged normally
After long-term use, Rinnai water heaters are easily affected by the outside world and can easily become loose or fall off, resulting in air intake and exhaust from the flue. It affects the normal opening of the air pressure switch.
2. Check whether there are foreign objects in the flue
Check whether there are foreign objects in the flue. If there is foreign matter, clear it out.
3. Check whether the fan of the Rinnai water heater is abnormal or not working.
Check whether the fan of the Rinnai water heater is abnormal or the rotation speed is very slow. If this happens, we need to clean or replace the Rinnai water heater fan.
4. Reset or restart the Rinnai water heater
Reset or restart the Rinnai water heater to see if it will resume working.
5. Power supply problem
Check whether the AC power plug indicator light is on, and first eliminate the problem with the power supply part.
6. Fouling in the waterway causes blockage of the hot water pipeline
, resulting in a large flow back pressure in the waterway. To a certain extent, the water and gas linkage device of the water heater will think that the hot water faucet has been closed and turn off the gas, and the fire will not start. Water lines need to be cleaned.
7. Hardware fault
If a fault still occurs after following the above troubleshooting, then to some extent the hardware is damaged.
1. For Rinnai water heaters with water temperature control, if code 11 occurs during use, it is usually because the water heater is not powered off. The reason is: electric heater failure. When the water heater is powered on normally but the electric heater is not powered off, such an alarm light will appear. If the electric heater is not powered on, code 11 does not appear. In this case, the Rinnai water heater should not be disconnected from the power supply.
Solution: Let’s first check whether the power supply of the electric heater is intact and normal? After checking that the electric heater is not damaged or completely disconnected, we then check whether this kind of alarm light appears; if the alarm light wire is burned out, it means that the electric heater is well powered and has not been completely disconnected; or the electric heater is The device has quality issues. If we still cannot determine the cause of the fault after inspection, we can only use a multimeter to point the electric heater to observe whether the voltage value is within the normal range and determine the fault status.
2. If there is no water in the home, the power may not be connected, causing the temperature control switch to not work properly.
If there is no water in your home, there may be pipes installed or fixed, causing the thermostat to not be able to connect to the power supply normally. In this case, it is recommended that you install the thermostat in a dry environment. If there is no water at home, please install the thermostat where there is a faucet and wipe the thermostat with a towel or soft cloth. If the power still cannot be turned on, it is recommended to contact a professional. Another situation is that there is water leakage in the forest (after all, water pressure also affects the water temperature), causing the water temperature control switch to fail to work.
3. If you are using a Rinnai water heater without water, but the temperature control switch often does not work or is completely out of power, it may cause damage to the internal components of the water heater.
Solution: If you are using a Rinnai water heater with waterless heating and the temperature control switch does not work, the internal components may be damaged. Because of the water pressure control function in this water heater, PTC heating tubes are used. When this happens, it may be necessary to replace the PTC or replace other components. Therefore, in daily use, the fault code should be changed to 11 in time. Another solution is to ask professionals to come to your home for repairs.
If the Rinnai water heater displays 11, it means the initial ignition is faulty. Damage to any component of water, gas, or electricity will cause the water heater to fail to ignite.
1. Scaling in the waterway causes blockage of the hot water pipeline, resulting in a large flow back pressure in the waterway. To a certain extent, the water and gas linkage device of the water heater will think that the hot water faucet has been closed and turn off the gas, and the fire will not start. It is necessary Clean waterways.
2. Check if there is no gas. This error will also occur if there is no gas.
3. Is there no power? If there is no power, the battery needs to be replaced.
4. If the hot water faucet has been fully opened recently and the hot water pressure is low, the possibility is greater. Since the igniter is normal, it is more certain. It is recommended to clean and descale first.
5. If the 11 fault code is still displayed after trying the above methods, then the solenoid proportional valve or the computer motherboard is broken, and you can only contact the brand for after-sales repair.
1. The Neng rate gas water heater will stop safely after opening the faucet for about 10 seconds, and the content of the water heater ignition is poor. The reason is poor ignition on the side of the water heater. If error code 11 is displayed, please turn off the operation switch and check that the gas valve is open. , or whether the gas meter cuts off the gas.
2. If it is LPG, confirm whether there is insufficient gas to use a gas stove, etc. If there are any problems above, please deal with them. If no problems are found, please report for repair.
3. During the trial operation, because there is air in the gas pipe, there will be no fire several times. Use the operation switch to reset and repeat until the water heater ignites. "Poor ignition of the water heater" may cause abnormalities in the ignition system and combustion detection device system, etc.
4. Common faults of energy water heaters - the outlet water temperature cannot reach the set value. When some users use it, the temperature has been set at the value they want, but they find that the water temperature cannot reach this value. Sometimes the water temperature is still Basically, it doesn't change much, and there may even be hot and cold situations. This situation is often caused by insufficient heat load of the machine. In summer, it is easier to heat, but in winter, the temperature is relatively low. Sometimes, the water pressure cannot be reached within the specified time, causing the water temperature to fail to rise, so it is difficult to achieve this situation. Therefore, the best solution is to replace a larger gas water heater, or reduce the water inflow.
5. Common faults of Nengli water heaters - gas water heaters cannot ignite. Sometimes, users will find that Nengli gas water heaters cannot ignite. At this time, they need to find the reason. The battery power is insufficient, the water pressure is insufficient, or the water pressure is insufficient. Insufficient pressure in the gas pipeline, or problems with the igniter, etc. may cause the gas to fail to ignite.
6. At this time, replace the battery, install a booster device at home, or ask the gas company to take a look. , or ask a professional to repair the gas water heater to provide corresponding services.
Rinnai water heater fault code 99
1. The temperature sensor is damaged
2. The message on the sensor. The source is broken.
3. Instrument control system failure.
When the solar temperature shows 99 degrees, you should first check whether the temperature sensor is damaged. You can only replace the solar sensor of the same model. If the temperature still shows 99 degrees, then check Is the signal source from the control system to the sensor broken? If the signal source is good, it can only be a fault in the control system, which can be solved by directly replacing the accessories of the same model. 7. Rinnai water heater shows 16 fault? Display 16 fault code means: circulating water pump failure, gas proportional valve failure, three-way valve failure.
1. If the three-way valve is faulty, the boiling water system and heating system of the furnace should be one. Everything is normal, but one cannot be used (warranty required)
2. If it is a failure of the circulating water pump, it will usually be accompanied by abnormal noise. Most of the time, the furnace's normal central heating pressure is adjusted to a high level. After two years of testing, the water pump will no longer work. The rolling bearing will be damaged.
3. If the natural gas proportional valve is faulty, it should not be able to start the fire or the flame will not change after igniting the fire.
4. If it doesn’t work, you can only ask the after-sales service to check.
