Kärcher pressure washer pump reported pulsating abnormally, indicating a potential mechanical defect.

“Karcher 3.97 Electric Pressure Washer pulsating pump [thread title from owner report]”

A hairline crack in a Kärcher pressure washer cylinder head caused pulsing failure, raising concerns about long-term build quality.

“Broken Karcher pressure washer [thread title referencing hairline crack in cylinder head causing failure]”

vs Marketing: Kärcher markets its products as robust cleaning tools; a structural cylinder head crack leading to failure contradicts implied durability, though again this applies to a pressure washer, not the SC 2 steam cleaner line.

Kohler Essex faucet cartridge found stuck and extremely difficult to remove despite manufacturer guidance suggesting straightforward removal.

“We have a Kohler Essex bar faucet that is dripping... the cartridges should just unscrew with a 5/8" socket [but they are stuck]”

vs Marketing: Not directly a Kärcher issue — this is a Kohler faucet complaint included in the dataset, suggesting data contamination across unrelated product categories.

Miele dishwasher auto door open feature reported as unreliable by at least one user.

“auto door open feature not working reliably [key phrase from Miele dishwasher discussion]”

vs Marketing: Miele markets auto-open door as a premium drying feature; unreliable operation directly contradicts this claim, though this is a Miele appliance issue unrelated to Kärcher steam cleaners.
