Common problems
Water purifier problems we repair in Dhaka
Different faults can produce almost identical symptoms. A blocked filter, failed SMPS adapter, weak booster pump, faulty solenoid valve, pressure switch, storage tank, or RO membrane can all reduce performance. We test the system first, identify the failed component, and explain the repair before recommending a replacement part.
No water from the purifier
No water usually points to a blocked sediment filter, failed SMPS adapter, weak booster pump, closed solenoid valve, or low inlet pressure. We test the electrical supply and water path to locate the component stopping the flow.
Water leaking from the unit
Leaks commonly start around filter housings, push-fit connectors, pipes, storage tanks, faucets, or damaged O-rings. Switch off the purifier and close its inlet valve if water is collecting under the unit.
Slow water flow
Blocked pre-filters, a restricted RO membrane, low inlet pressure, or lost storage-tank pressure can slow purified-water flow. We test each point before recommending a new filter or membrane.
Pump running continuously
A booster pump that doesn’t stop can indicate a faulty high-pressure switch, leaking storage tank, blocked membrane, open flush valve, or pressure loss. Keeping it running may damage the pump and power adapter.
Unusual noise or vibration
Grinding, knocking, or constant humming can come from a dry-running booster pump, loose mounting, low water pressure, trapped air, or a failing solenoid valve. Switch the purifier off if the sound suddenly becomes louder.
Bad taste, smell, or high TDS
Changes in taste or smell may come from an exhausted carbon filter, old membrane, contaminated storage tank, or water bypassing a treatment stage. We compare inlet and purified-water TDS and inspect the complete filtration path.

Check first
3 safe checks you can make before booking
Check the power supply
Look for a light on the adapter and test the wall socket with another device. A failed socket or disconnected adapter can make a working purifier appear completely dead.
Open the inlet valve fully
The inlet valve must be fully open. A partially closed valve can reduce water pressure, slow production, and cause the booster pump to run louder.
Check the building’s water supply
Confirm that water is reaching the kitchen or purifier inlet. An empty reservoir, stopped building pump, or temporary WASA pressure drop can prevent an RO purifier from starting.
Do not open electrical parts, pressurised filter housings, or internal pipes unless you have the correct tools and experience.

Customer stories
What Dhaka customers say about our repairs
Feedback from customers who booked a WPSBD water purifier repair.
Three technicians before could not fix my purifier. WPSBD found the problem on the first visit, replaced one part, and it has worked since.
WPSBD checked the machine, told me the price, and the final bill was exactly that. No extra charges after opening it like last time.
Called in the morning with no water at all. WPSBD came the same afternoon and fixed it. Would have liked an earlier slot though.

Water purifier repair: questions we get asked
How much does water purifier repair cost in Dhaka?+
The technician visit and fault diagnosis cost ৳299. After inspection, we price the repair labour and replacement parts separately. The technician explains the fault and complete repair price. We begin paid repair work only after you approve it.
My purifier stopped working completely. Can it be repaired?+
In many cases, yes. A purifier that doesn’t turn on may have a failed SMPS adapter, booster pump, pressure switch, wiring connection, or blocked treatment stage. Diagnosis identifies the failed component and whether repair or replacement offers better value.
How long does a water purifier repair take?+
A technician can reach most Dhaka addresses within 90 minutes of booking confirmation. Repair time depends on the diagnosed fault and required part. After inspection, the technician explains whether they can complete the repair during that visit and how long it should take.
Do you repair purifiers you didn't install?+
Yes. We repair supported RO, UV, UF, and multi-stage purifiers regardless of where they were purchased or installed. Share the brand, model, approximate age, and symptoms when booking so the technician can prepare the correct sealed, brand-original parts.
Is it worth repairing an old purifier, or should I replace it?+
Repair stays economical while the cabinet and storage tank are sound and 1 component has failed. Replacement wins once a housing is cracked or 3 expensive parts fail together. We price both options after the diagnosis so you can compare real numbers.
What does the 7-day water purifier repair guarantee cover?+
If the same diagnosed fault returns within 7 days, WPSBD provides the revisit, repair labour, and replacement part used for that repair without another charge. We diagnose and price a new or unrelated fault separately.
