Aquaguard — Continuous beeping on Aquaguard purifiers is an alarm that signals one of several conditions: the filter or UV lamp service is due, the storage tank is full (overflow protection), inlet water pressure is too low, or a sensor has malfunctioned.

Aquaguard — Error E3 on Aquaguard purifiers (Enhance, Aura, Geneus, Marvel series) indicates the UV disinfection lamp has either burned out, lost electrical contact, or the UV sensor is not detecting sufficient UV output.

Aquaguard — Low water output pressure on Aquaguard purifiers means the unit takes significantly longer than usual to fill a glass or the water stream is noticeably thinner than when the purifier was new.

Aquaguard — When an Aquaguard purifier stops dispensing water entirely, the cause is usually one of four things: the inlet water supply is interrupted, a pre-filter is severely clogged, the RO membrane is fouled or the auto-flush solenoid valve has failed.

Aquaguard — A blinking red indicator on Aquaguard (Eureka Forbes) purifiers signals that the UV lamp has failed or has reached end-of-life.

Kent — Error E1 on Kent RO+UV purifiers indicates the inlet water pressure has dropped below the minimum threshold (typically 5 PSI) required to push water through the RO membrane.

Kent — Error E2 on Kent RO purifiers indicates the float valve or tank full sensor inside the storage tank has malfunctioned.

Kent — Kent RO purifiers track filter life via an internal timer.

Kent — Water pooling under a Kent RO purifier typically originates from loose push-fit connectors, cracked filter housings, deteriorated O-ring seals, or a punctured membrane housing.

Kent — A Kent RO purifier that gives no water, or only a slow trickle, usually comes down to water not being able to get through the system.

Kent — A blinking red light on a Kent purifier is a status alert, not necessarily a breakdown — but the distinction matters: on most Kent models a steady red LED simply means the unit is powered on, and a green LED means it is purifying, both of which are normal.

Kent — When the UV lamp fails or degrades, Kent purifiers display a UV lamp alert (typically an orange or red indicator) and may stop dispensing water or continue dispensing unsterilised water depending on the model.

Livpure — Bad taste or odor from a Livpure water purifier typically indicates an exhausted post-carbon filter, bacterial growth in the storage tank, stagnant water from infrequent use, or contamination from a degraded RO membrane allowing source water flavour to pass through.

Livpure — A Livpure RO that keeps running and sending water to the drain even when the storage tank is full has an auto-shut-off failure.

15 min · intermediate

Livpure — Error E1 on Livpure RO purifiers (Glo, Pep Pro, Zinger, Bolt+, Envy series) indicates that the low-pressure switch has detected insufficient inlet water pressure.

20 min · beginner

Livpure — When a Livpure water purifier motor (RO pump) fails to start, the unit may appear completely dead, hum without pumping, or start then immediately stop.

30 min · intermediate

Livpure — When a Livpure RO purifier stops reducing TDS effectively (output TDS is close to or the same as inlet TDS), the RO membrane has either failed, been damaged by chlorine exposure, or a bypass fault in the internal tubing is routing unfiltered water directly to the storage tank.

Pureit — Pureit (HUL) water purifiers use a proprietary Germkill Kit (GKK) instead of separate filter cartridges.

15 min · beginner

Pureit — Reduced water output from a Pureit purifier (water drips instead of flowing steadily, or the tank takes much longer to fill than it used to) indicates one of four problems: low inlet water pressure, a partially exhausted or clogged Germkill Kit (GKK), a fouled RO membrane in RO models, or a blocked dispensing tap.
