Hotpoint Dishwasher Spray Arm

The rotating arm that sprays water onto the dishes from below or above.

DifficultyEasy

Typical time5 to 10 minutes

ToolsNone or a screwdriver

Safety. Unplug the dishwasher and turn the water off before you start. Keep towels and a tray ready for trapped water.

Signs it has failed

Dishes coming out dirty in one area
A cracked, broken or warped arm
The arm does not spin freely
Blocked spray holes

Check before you buy

Remove the arm and clean the holes with a pin or toothpick
Spin it by hand: it should turn freely on its mount
Check for cracks or a worn bearing at the centre

What replacing it fixes: if the signs above match your dishwasher and the checks point to this part, fitting a new one should clear those faults. If the symptoms continue, the cause is elsewhere (a control board, a sensor or a blocked vent or hose).

How to replace it

Open the dishwasher and remove the lower rack
Unscrew the retaining nut or twist the arm off its mount
Fit the new arm and secure it
Spin it to check it turns freely
Run a short cycle

Guide steps are typical for this type of part. Layouts differ between models, so follow your own manual where it differs.

Getting the right part

Arms vary by position (lower, middle or upper) and mount type. Match the part number or your model number.

Check your model number first. It is on the rating plate — usually inside the door frame, on the back or side panel, or inside the appliance. Parts that look identical often differ by model, so match the number to the listing before you order.
