What this usually means
A dishwasher makes a predictable set of sounds — filling, spraying, draining — and a new noise is usually something loose in the tub, a spray arm hitting a dish, or a pump with debris in it. A machine that is not level or not secured to the worktop is the first thing to suspect on a Crosley, because these units change homes more than most, and levelling, hose routing and venting are what the move breaks first. Loose items, loading and filter debris are owner work; a wash pump or motor bearing is not.
What the machine is doing
- A rhythmic knocking during the wash — A spray arm striking something in the rack on every sweep.
- A grinding or buzzing during the drain — Glass, a label or a bone fragment in the pump.
- A high whine that rises and falls — The wash pump running against a restriction, or cavitating on a low water level.
- NEAR MISS — Clicking during the fill — The inlet valve, and it is normal on most machines.
Likely causes in order
- A machine that is not level or not secured to the worktop — Top of the list on this brand: these units change homes more than most, and levelling, hose routing and venting are what the move breaks first. A built-in machine is meant to be fixed to the cabinet or worktop; unsecured, it buzzes against the units as the pump runs.
- Water hammer or a restricted inlet — Second most likely: A bang as the machine stops filling is water hammer in the house plumbing rather than a machine fault, and it can be loud enough to alarm.
- A spray arm hitting a dish or a rack item — Third most likely: A tall glass, a handle hanging through the rack or a pan lid leaning over the arm makes a regular knock that follows the arm’s rotation.
- Glass, labels or bone in the sump and pump — Fourth and the least likely here: Hard debris passes the coarse filter and reaches the impeller, where it rattles for the whole cycle and eventually jams something. The service history is usually unknown, so the filters and seals are older than the owner thinks.
The order to work in
- Press on the door front and see whether the machine moves in its housing — Movement means the fixings are loose or missing, which turns normal vibration into noise. Start here: on this platform it is both the most likely finding and the quickest to confirm.
- Note whether the bang happens at the moment the fill stops — A single sharp bang at valve closure is plumbing, not the appliance.
- Spin both spray arms by hand with the load in place — If either catches, the noise is explained and the load is the fix.
What an owner can safely check
- Check the fixing brackets at the top or sides and level the feet — Adjust the feet until the machine is stable, then refit the brackets.
Tools: screwdriver, spirit levelAbout 25 min
- Reload so nothing protrudes into the arm’s path and spin the arms by hand to confirm — Handles pointing down, lids to the sides, nothing through the rack wires.
About 10 min
- Stop here if the next move needs a meter on live terminals — That is where an owner check ends and a service call begins.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close the taps before any hose comes off, and never bypass a door or lid switch to run the machine open.
When to call a technician
Call when the tub is clear, the arms spin freely, the sump is clean and the machine is secure, and the noise continues — a pump or motor bearing needs the machine pulled out and opened.

How specific this page is
This page covers Crosley dishwashers as a class, not one family or model line. There is no per-model page under this one today. Where one appears it is linked from this block and it is the page to trust for a specific cabinet. Deliberately not here: wiring colours, resistance values, torque figures and part numbers, which differ between families.
