24-hour national unified 400 service line 400-186-3315 for the maintenance of intra-forest water heaters
National unified advisory centre for forest water heaters
National service area for water heater maintenance in the forest: all regions of the national network have an inner electrical service point to arrange for a teacher close to home and fast-track service
Telephone maintenance in forest water heaters and telephones in the country 24-hour centre
The national hotline for forest water heaters offers 24-hour appointments for home service, on saturdays and holidays, on appointment, fast-tracking, and maintenance and maintenance. Owing to uncertainty over the causes of the failure, it was not possible to harmonize the quotations on the telephone, and all fault-type repairs were subject to on-site testing, with no cost。
Type of maintenance
Gas heater maintenance, electrical heater maintenance, solar maintenance, air heater maintenance, installation, cleaning。
Four common causes of failure and solutions for water heater maintenance
1: during heating of water heaters, the small hole of the safety valve is dripped. This is a common phenomenon。
Reason: because the water heater is a closed water-storage electric heater, during heating or temperature protection, the water pressure in the water heater is greater than 6 mpa, which causes a one-way safety valve to spill and drop the bead。
Solutions: close the water valve and shift the mixed water valve to high temperatures to avoid leakage from the one-way safety valve and to cause water to drop from the flowers. In the absence of a mixed water valve, a little heat-ball valve can be opened, where the flow of water is discharged, or leakage from the one-way safety valve can be avoided。
#2: the water heater leaks during use. This is a serious malfunction that requires constant attention。
Reason analysis: the wind switch was inappropriately adjusted. Inhalation is inappropriate. Silicon ducts or tortex cracks cause a leak of air pressure that does not drive the wind film. Wind pressure switch failed. Pulse failure。
Solutions: regulate wind-pressure switches to the right position. Regulates the inhaler. Inserts or replaces a silica tube. Change wind pressure switches. Change pulser。
Three, failure three: self-activated power outages (regular automatic jumps) from electrical protection plugs during use, re-entry of power by pressing the sub-key。
Reason analysis: usually due to abnormally high temperatures due to poor interpolation exposure. Lightning, lightning strikes, or a leak to the ground from adjacent appliances, among other things, will allow currents to trigger leak protection plugs in the surface line。
Solutions: replacement of high-quality plugs (selections, extractions, plugs, bites). Check for several copper plugs of leak protection plugs. If blackened, the oxidation layer is wiped out with sandpaper, and if the foot is deformed, it should be amended and the three copper feet should remain vertically to the bottom and not bend。
4: fault four: difficulties in water entry or exit。
Reason analysis: obsolete. The main ones are poor water quality and impurities, blocking the inverse valves of the water intake. The electric water heater with a filter is due to the blocking of the filter hole, the blockage, the abnormal pressure on the water supply and the failure of the mixed valve。
Solutions: after determining normal water pressure, clear the pipes, hit the dirt or wash the filter, move the thermostat to* small positions or power cuts, steam discharges, repairs temperature controls and hot water valves, adjusts and washes, and when the water pressure is normal, the failure itself disappears, repairs or replaces the mixed water valves。
Maintenance prices
No door and test fees are charged for maintenance. Owing to the different types, brands and specifications of water heaters, it is necessary for the maintenance master to conduct an inspection and then offer a price based on the size of the failure. New and old clients are welcome to consult!
Service commitments
1. An hour after the receipt of a telephone call to arrive at the site, free of door fees and unfeeable repairs。
2. There are cost savings for customers in terms of spare parts。
If you have the same problem within two months of maintenance, you will be served free of charge by a telephone call。
