Need to repair the Oasis geyser? German-made equipment is notable for high-quality assembly, but not without breakdowns. If your gas heater does not work, leaks or goes out, read our article. We will tell you: how to determine the breakdown, how to deal with problems with your own hands, what measures to take so that the equipment does not break down anymore.
The main causes of the malfunction, their elimination
The designs of all geysers are similar to each other. Why not summarize all the problems and not describe the options for solving them? Because each brand has its own weaknesses. Then there are malfunctions characteristic of specific brands. We analyzed user reviews to collect reliable information for you.
In Oasis water heaters, factory marriage is extremely rare. Device Diagram:
The cause of the breakdown can be external and internal factors:
- Incorrect installation and connection.
- Incorrect operation.
- Clogged chimney and ventilation.
- Problems with internal components: scale, corrosion.
The solutions to these problems are described below.
The column does not light
There can be many reasons, we will help you figure it out. The main thing is to correctly determine the place of failure.
If the device does not ignite at all, a spark is not generated, then:
- The batteries are low. Devices with automatic ignition operate on battery power. To replace, take quality elements with a good charge. If you find leaks at the installation site, strip all contacts and install new batteries.
- Traction problems. For normal operation of the equipment, there must be draft in the chimney. If not, inspect the ventilation hole for clogging. It can be a foreign object, soot or rubbish from the street. If possible, clean the hole. Make sure that the chimney outlet is not blocked from the outside.
How to find out if there is traction? Light the back, bring the speakers to the viewing window. The flame deviates - there is draft, burns exactly - no. You can also lean a sheet of paper against the ventilation. If there is traction, the sheet will be pressed to the output, otherwise it will fall.
- Water pressure regulator set to minimum. A small pressure is created in the system to trigger the membrane and open the gas valve. Set the control to the maximum value.
- Low line pressure. When opening the tap, a thin stream flows? Contact the water utility and wait for the flow to resume. If this happens often, it is recommended to install a circulation pump.
- Strainer clogged. The part is located at the entrance to the water unit, it retains small debris that comes with the flow of water. It is necessary to disassemble the unit, rinse the filter under running water.
- Membrane stretched. The element serves to start the gas valve. With pressure in the line, the membrane stretches, pushes the stem and opens the valve. Over time, she wears out, so she needs a replacement. You can read about it here: “Water column of a gas column”.
- Micro switch failure. It cannot be repaired, so a replacement is needed.
- Wiring problems. Remove the cover, inspect all wires leading to the control unit. If insulation is broken, replace the cable.
- Solenoid valve malfunction in the gas unit. It is necessary to inspect, check and install a new part.
Column flowed
Leaking is a serious malfunction, but you can cope with it yourself.
Oil seal flows through the stem.. To verify this, remove the cover and check where the water flows.
How to do an independent repair:
- Remove the adjustment knobs by pulling them towards you.
- Unscrew the four screws securing the casing.
- Disconnect display wiring.
- Remove the batteries from the unit and remove it by unscrewing the bolt from the bottom.
- Disconnect water hoses.
- Remove the water valve bolts, remove it.
- You got to the gland and its stock. When dismantling the old rod, the gasket may remain inside - this is not scary. Just remove the gasket from the new part and install.
- Assembly is carried out in reverse order.
A more serious problem is leak in the radiator. The new heat exchanger stands almost like the new Oasis Turbo model. How to save? Overlap fistulas by soldering. More details in the article “How to solder a gas column”.
The easiest way to eliminate the leak is if a hole has formed on the outside of the tube. Then you can use cold welding. Internal corrosion requires the use of a soldering iron or torch with a temperature of 170 degrees. As a flux, rosin or an aspirin tablet is suitable.
Before starting work, prepare a radiator:
- Drain the pipes.
- Dry.
- Strip the place of soldering with fine sandpaper.
- Wipe with a degreasing agent.
You can start the repair. So that the fistula no longer appears, the thickness of the solder should be 2-3 mm. Inspect the node for green spots - these are future fistulas. It’s better to take care of them right away.
Heat exchanger clogging
How to understand that the radiator is clogged:
- Prolonged heating of water.
- The stream is not hot, but warm.
- Scum pieces come out with water.
These are indirect signs, therefore it is better to inspect the device. Scale on the plates of the heat exchanger and the coil appears from poor-quality water and high heating temperature. It is recommended to set 55 ° C and not mix flows on the mixer.
There are two ways to get rid of the blockage.
- Without removing the assembly from the column. You will need a special pump with tubes. A reagent is poured into it, which can be bought in a store or made on the basis of hydrochloric acid. Connect the hoses to the coil and start pumping until all the scale comes out of the holes.
- With dismantling. This is a budget option. A deep tank is filled with water, a heat exchanger is lowered into it. A solution of citric acid (150 g / 750 ml) is poured into the coil through a watering can. The container is placed on the stove and boiled for 15 minutes. Then the radiator is washed under running water, dried and installed in place.
The smell of gas when turned on
This is a serious and dangerous malfunction. Shut off the gas supply immediately! Contact the gas service.
The stuffing box is probably worn out. Gas leak replacement must be carried out by a specialist. How to disassemble the gas-water unit and get to the gland, we described above.
Starting to operate the equipment, read the instructions. It is recommended once a year to conduct a routine inspection of all components of the water heater. Now you know what to do. And if you are confused, shut off the fuel supply and contact a service center.
