I replaced the water inlet valve on my Whirlpool WRS555SIHZ06 yesterday. Since then, the ice maker is putting too much water into the tray, so the cubes are freezing together into one large block.

I have the Whirlpool diagnostic/service sheet and it includes an Ice Maker Water Fill Test with a target of about 100 mL ± 10 mL.

My questions are:

1. Is the ice-maker water fill amount adjustable on this specific model?
2. Is there a mechanical adjustment screw, or is fill time controlled electronically?
3. If the measured diagnostic fill is over 110 mL, would that point more toward the replacement inlet valve having a higher flow rate than the original?

The problem started immediately after replacing the valve, so I’m trying not to adjust the ice maker unless this model actually provides a proper fill-volume adjustment.

Thanks for any help.
