Frequently occurring fault in water purifier:

1 Water Leakage:
One of the most frequent water purifier problems is concerned with water leakage. If you notice a pool of water
beneath an RO, do not get intimidated. Most often than not it might be due to the loose connections of pipe
connectors.
To fix this, the faulty connection needs to be refitted properly or sometimes even replaced. If the leakage is in the
membrane, the O ring (the soft rubber ring that stops water from seeping into other parts), might be damaged
and would need replacement. It is a good idea to seek professional help if you notice any sort of water leakage
in your RO water purifier.

2 RO not working:
If your RO does not give any water output and the storage tank is nearly empty, it can be quite frustrating. First
off, check if the switch button is turned on properly and that you have an electricity supply. In case both these are
positive, the fault may be with the power supply connector. In this case, it is prudent to seek professional help.
If the power indicator is in the ‘on’ mode and the water supply is not resumed, check if the water supply valve is
turned off. If so, turn it on and check if the RO water filter is working properly.

3 Bad odor and disagreeable taste of water:
In its natural state, the RO water filter, do not give off foul-smelling or tasting water. If you experience either of these
two conditions with your RO water purifier, it may be due to the presence of chlorine in the water. This is most
commonly due to the filters not working properly. To avoid this, it is recommended that you change the filters yearly.
4 Auto shut-off feature not working:
In normal cases when the water stocking tank of the RO water purifier gets filled over the designated levels, it
stops all cleaning activities and shuts itself off. In case this feature is faulty, the machine continues to operate,
and the water will begin to seep out of the crevices and begin to leak out. In such cases, a professional should be
called in to fix this flaw, immediately.
Strange noises:
If you hear unusual-sounding noises coming out of your RO water filter, especially after replacing the membranes,
it could be due to the air being pushed out of the system or due to a sudden change in the water pressure. If the
noise does not subside in a while, it might be a good idea to call a technician to check if the tubes are properly
connected and to ensure that the water tank’s valve is properly closed. They might also need to replace the RO
pump, as with constant use, it can become noisy.

6 Low water output or water tank takes a long time to fill:
The filter in your RO water purifier is designed to filter out all sorts of impurities. In the process, some of the
contaminants may get stuck to its surface, blocking the proper flow of water through it. If the filters are not cleaned
frequently, this can even form a patina-like layer on the membrane. This is especially common in areas where the
water quality is very bad. The solution to this problem is to check your filters and get them cleaned or replaced
consistently.
Immersion heater:
Immersion heaters are electric heating elements that are found inside hot- water cylinders and designed to heat
water. They act a little like a kettle and heat the surrounding water in the cylinder.
