Common malfunctions
1. Water drops from the safety valve
During heating of water heaters, the small hole in the safety valve is dripped. This is the most common phenomenon. Dripping cause: because the electric water heater is a closed water heater, the water pressure within the water heater is greater than 6 mpa during heating or temperature preservation, which causes a one-way safety valve to spill out 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. Short use of hot water
Reason analysis: the first use of water heaters (or, in some cases, unserviced and new ones) results in low heat discharges due to the short heating time of the water heaters and uneven temperatures in the upper and lower layers. Solutions: work for more than 12 hours on a continuous basis using water heaters, so that the water temperature within the water heaters is evenly flat。
3. Power leakage during use
Power leaks during the use of water heaters. This is a serious malfunction that requires constant attention. Reason analysis: 1 wind-pressure switch was inappropriately adjusted; 2 air-breeding mouth was inappropriately located; 3 silica tubes were released or tortex fractures resulted in leaking pressure that could not drive the wind film; 4 wind-pressure switches failed; 5 pulsers failed. Solve: 1 to regulate the wind pressure switch to the right position; 2 to regulate the inhaler mouth; 3 to insert or replace silicone tubes; 4 to replace wind pressure switches; 5 to replace pulsers。
Four, signal lights on, but no heating
Reason analysis: 1 heat pipe interlocking end was poorly exposed or broken; 2 heat pipes were burned. Solutions: 1 check exclusion; 2 replace heaters。
Five. The signal light is not on and it's not heating
Reason analysis: 1 temperature controller plug-in or cut-off; 2 temperature controllers burned; solution: 1 check excluded; 2 replace thermostats。
Six, the water heater's light is still on
Reason analysis: 1 temperature temperature temperature with little contact point for electrothermal piping; 2 temperator is bad. Solutions: re-installation of thermostats to reach the temperature plane; replacement of thermostats。
7. Self-use power outages
In the course of use, the power protection plugs are self-activated (a regular automatic jump) and can be restored by pressing a double-bit key. Reason analysis: 1 — usually due to abnormally high temperatures due to poor interposition exposure — 2 — lightning, lightning strikes, or a leak to the ground from adjacent electrical appliances, etc. — allows currents to trigger leakage protection plugs at short notice. Solutions: 1, replacement of high-quality plugs (selecting, extraction, plugging, biting, etc.); 2, inspection of several copper plugs in leak protection plugs and, if darkened, wipe the oxidation layer with fine sandpaper, which, if deformed, should be amended and three copper feet should remain vertical to the bottom and not bend。
8. Water not hot
Reason analysis: 1; inadequate cool and hot water regulation; 2; power not connected; 3; electrical heater damage; 4; temperature control damage. Solutions: 1; properly adjust the opening of cold and hot water mixed valves; 2; adjust power plugs or switches for good exposure; 3; replace electric heaters; and 4; repair or replace thermostats。
The water's too hot
Reason analysis: 1: inappropriate cool and hot water regulation; 2: inappropriate or adhesive thermostats. Solutions: 1; properly adjust the opening of cold and hot water mixed valves; 2; first adjust the thermostat and then repair the contact points and replace the thermostat if necessary。
10. Water in or out difficulties
Reason analysis: 1, dirty. 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 because the filter hole is blocked; it's blocked; it's blocked; it's blocked; it's under abnormal water pressure; and it's mixed valve failure. Solutions: 1. Cleaning of pipes, impacting of stains or cleaning of filters after a normal water pressure has been determined; 2. Move the thermostats to a minimum position or cut the power source, ejecting steam, overhauling temperature controls and hot water valves, adjusting and cleaning; 3. When the water pressure is normal, the failure itself disappears; 4。
Selection error
Power outage and outage
The effect is to automatically cut the power at the time of use and to use a safety device for the complete automatic restoration of power. The possibility of electrocution cannot be avoided in practice, as it is simply cutting off the power supply when the water comes out and, if there is a risk of a leak at this time, when the water is turned off, it is caused by the restoration of electricity. In addition, if the power is leaked before use, it is triggered by contact with a metal cut-off. Safe use should be through the installation of reliable ground lines in electric water heaters and the use of power lines with leaks。
Water and electricity separation structures
Some plants have deliberately emphasized that they are water-separated heating tubes, whereas the heating tubes used by electric water heaters are separated by hydropower. And it is highly safe as long as it is manufactured according to relevant standards. Most electro-heaters use direct heating tubes, which have the advantage of being heat-efficient, durable and simple in their manufacture。
Magnesium bar act
Almost all manufacturers have promoted the role of magnesium rods as “the strong removal of dirt, softening of water quality, and the protection of skin”. In fact, the magnesium bar actually acts as a preservative, but it hardens the quality of water, leads to severe contusions and, of course, adversely affects the skin。
You've got a lot of nerve
In an era of increasingly “homogenized” goods, it should be said that state-owned water heaters are technologically high and, in some respects, outpaced. Moreover, state brands have a clear advantage in terms of prices, familiarity with geographical culture and after-sales services. As a result, there is no absolute basis for spoiling the brands and technologies of the oceans, and this mentality is easily exploited by some poor-quality national goods in the market, which are based on “ocean manufacturing, ocean technology”。
