Haier dryer displays CL and buttons do not respond.

Safety first: No internal work is required for normal child lock operation.

• Disable child lock: Press and hold the designated child lock button combination (often two specific buttons) for 3–5 seconds. Refer to the user manual for your exact model.
• Check button function: If CL will not clear, press each button to ensure none are stuck. Clean the panel surface.
• Power reset: Unplug the dryer for 5 minutes, then reconnect and try disabling child lock again.
• UI board replacement: If CL remains stuck and buttons do not respond, the user interface board may be faulty and require replacement.
