• How do I clean the filter on my Koblenz wet/dry vacuum?

  Change or clean the filter frequently for peak performance. Remove the filter carefully, wash it if it is a washable/reusable type (like HEPA or cloth filters), check for holes, and let it dry completely (at least 24 hours) before reinstalling.

• Can I use my Koblenz vacuum without a filter?

  Never vacuum solids or use the air expulsion system without the filter installed, as this will damage the machine and invalidate the warranty. However, you must remove the paper filter when vacuuming liquids to prevent damage.

• Why did my Koblenz food processor unexpectedly stop?

  Koblenz blenders and food processors feature overload protection to prevent motor damage. If it stops processing, unplug it and let the motor cool for at least 30 minutes before plugging it back in.

• Who do I contact for Koblenz warranty repairs?

  For warranty repairs, deliver the inoperative machine and proof of purchase to an authorized Koblenz service center or Thorne Electric Company. Warranty periods and terms vary by product (e.g., 5 years for certain vacuums, 2 years for kitchen appliances).

• How should I descale and clean my Koblenz coffee maker?

  Dilute three cups of vinegar in nine cups of water and pour into the reservoir. Turn on the coffee maker for one minute, switch off, and let rest for half an hour. Then switch on to finish the cycle. Run two complete cycles with just fresh water afterwards to remove the vinegar taste.
