What happens if you don’t change your filter?

If you don’t change the filter in your Thermador refrigerator, you may begin to notice some symptoms like hollow ice or a slow water flow. What you may not notice, is that the filter cannot continue removing contaminants from the supply water so it passes them on to you. This may affect the taste of the water as well as how efficient the filter is.

Conclusion

Thermador refrigerators that dispense water and ice are so convenient. Be sure to keep your water and ice clean and tasting great by replacing the water and ice filter at least every 6 months with an approved filter. If you know your filter number, it’s easy!
