Frequently Asked Questions - JSD12-6DH4 MIDEA
How do I ignite the water heater?
Ensure the gas supply is on and the batteries are installed. Turn the water heater control knob to the ignition position and press the piezo igniter button until the pilot flame lights. Then turn to the desired temperature setting.
Why does the heater shut off after a few seconds?
This may be due to a faulty thermocouple or low water pressure. Check the water pressure is above 0.02 MPa and clean the thermocouple. If the problem persists, contact a technician.
What size of gas pipe do I need?
The gas inlet is G 1/2". Use a flexible gas hose or rigid pipe with the same thread size. Ensure the gas supply pressure matches the heater requirements (2000 Pa for natural gas, 2800 Pa for LPG).
Can I use this heater in a bathroom?
No, this is a flued gas water heater and must be installed in a well-ventilated area. It should not be installed in bathrooms or bedrooms. Follow local installation codes.
How do I clean the water heater?
Disconnect the power and gas. Clean the exterior with a damp cloth. Do not use abrasive cleaners. The burner and flue should be inspected annually by a qualified technician.
How long do the batteries last?
Typically 6-12 months depending on usage. Use D-type (R20) alkaline batteries. Replace them when the ignition becomes weak or the heater fails to light.
What does the error code 'E1' mean?
Error code E1 indicates flame failure. This could be due to a blocked flue, low gas pressure, or a faulty thermocouple. Check the flue for obstructions and ensure the gas supply is adequate.
Does this heater work during a power outage?
Yes, because it uses electronic ignition powered by batteries. It does not require mains electricity to operate. Ensure the batteries are fresh.
What is the warranty period?
Midea typically offers a 2-year limited warranty from the date of purchase. Warranty covers manufacturing defects. Proof of purchase is required.
Can I adjust the water temperature?
Yes, the heater has a stepless manual gas valve that allows you to adjust the water temperature from low to high. Turn the knob to increase or decrease the flame size.
