Dishwasher displays E18; unit may run but water level is inconsistent and sometimes too high or too low.

Safety first: Disconnect power and water supply before servicing.

• Locate pressure switch: On some Crosley dishwashers, a small round pressure switch is mounted on the side of the tub or base with a thin hose attached.
• Inspect pressure hose: Remove the hose and blow through it to ensure it is clear. Clean any debris or grease from both ends.
• Clean level chamber: If the hose connects to a small chamber on the tub, clean this chamber to ensure water can move freely in and out.
• Test pressure switch: With a multimeter, check continuity while gently blowing into the switch. It should click and change state. Replace if it does not respond.
• Reassemble and test: Reconnect hose and wiring, restore power and water, and run a cycle to confirm stable water levels.
