Product Description
This is the 3W, 2/3rpm timer motor (Autotrol part number 1000098) that drives the control clock in an Autotrol 460i water softener valve. WrekinWater supplies it as a genuine replacement when the motor slows, stalls or stops advancing the regeneration timer. It's tagged as part of the wider 255/400 Autotrol valve family too, so check your control head model before ordering if you're not certain.

Signs this needs replacing
- The softener no longer regenerates automatically at its set time.
- The control clock's dial or display has stopped advancing.
- You can hear the motor buzzing but the timer doesn't move.
- Regeneration starts but stalls partway through a cycle.
This small geared motor drives the timer mechanism inside the Autotrol 460i control clock, advancing it through each stage of the regeneration cycle at the correct speed. As the motor wears or its gears stick, the clock can slow down, stall, or stop turning altogether, so the softener misses its scheduled regeneration and starts letting hard water through even though the valve itself is otherwise fine. Because it's a low-voltage part inside the control head, it's a straightforward fix once you know it's the cause.
WrekinWater has supplied genuine softener parts to more than 50,000 customers over 15 years from our Bettisfield, Shropshire base, and we're rated "Excellent" on Trustpilot. We stock the correct Autotrol motor so your 460i clock gets a proper fit rather than a generic substitute.
How to replace it
- Isolate the softener's power supply by switching off and unplugging the control head's transformer.
- It's worth isolating the water supply to the softener too, in case the valve is mid-cycle when you open it up.
- Remove the control head cover to expose the timer motor.
- Unclip the wiring connector and undo the retaining screws holding the old motor in place.
- Fit the new motor, reconnect the wiring connector, and refit the cover.
- Restore power and water, then run a manual regeneration to confirm the clock advances correctly — if it doesn't, have a qualified water treatment engineer take a look.
