Water flow becomes weak after a refrigerator filter change

Write down whether flow became weak immediately after the change or had already been declining. Save the replacement filter’s part number and packaging, along with the date it was installed. A filter that appears similar is not necessarily the correct part for the refrigerator model, and the installation instructions must match that filter system.

Thermador identifies correct filter installation and water-supply conditions as relevant to dispenser flow. Follow the model’s replacement and flushing instructions using only accessible owner-service steps. Do not disconnect supply tubing, bypass required components or force the filter housing if it resists normal installation. Stop if water begins leaking.

Note whether the dispenser produces a weak continuous stream, sputters or stops completely, and whether ice production changed at the same time. Explain any recent plumbing work or household water interruption. Those observations help separate a filter-related timing issue from a broader supply or appliance concern without pretending that one symptom proves the cause.

Useful observations before you call

• Send the refrigerator model and the exact filter part number.
• Record the previous and current filter-change dates if known.
• Report leaks, dispenser noises and whether other water fixtures changed at the same time.
