Sinkmaster 750: Jam Clearance and Splash Guard Service Cover Most Repairs
The Sinkmaster 750 is a continuous feed disposer with an induction motor and stainless steel grinding components. The most common service call on any garbage disposer including the Sinkmaster 750 is a jammed grinding plate from a foreign object like silverware, broken glass, or large food pieces that bypassed the splash guard. The hex wrench port on the bottom of the unit and the reset button handle this condition without any parts replacement. When parts are needed, the splash guard is the most commonly replaced component, as it deteriorates from repeated contact with hot water, grease, and cleaning chemicals over years of use.
Most Replaced Parts on the Sinkmaster 750
Splash Guard for the Sinkmaster 750
The splash guard on the Sinkmaster 750 sits at the drain opening and prevents water and food debris from splashing back up through the drain during operation. It deteriorates from repeated exposure to hot water, acidic food waste, and cleaning chemicals, eventually cracking or losing its flexibility. A damaged splash guard that allows persistent splashing should be replaced rather than cleaned, as the deteriorated rubber cannot be restored to adequate flexibility.
Mounting Assembly for the Sinkmaster 750
The mounting assembly secures the Sinkmaster 750 to the sink drain flange and allows the unit to be locked and unlocked for removal and reinstallation. Worn or cracked mounting components cause the disposer to wobble, vibrate excessively, or drop away from the sink during operation.
Power Cord for the Sinkmaster 750
The power cord on the Sinkmaster 750 connects the disposer motor to the wall outlet or hardwired junction box. A cord that has been cut, melted by contact with a heat source near the under-sink cabinet, or damaged at its connection point requires replacement.
