Disposal runs but the dishwasher does not drain properly when connected through the disposal.

Safety first: Turn off power to both disposal and dishwasher.

• Check inlet spigot: Remove the dishwasher hose from the McAlpine spigot and clear any debris inside the spigot.
• Inspect hose: Straighten any kinks and flush the hose with water to remove blockages.
• Install high loop: Ensure the hose rises above the sink level before dropping to the disposal to prevent backflow.
