FAQ

Can I use the dishwasher if the glass racks are wobbly?

It is not recommended, as it can cause further damage to the racks or the dishwasher itself.

How often should I check the glass racks for damage?

It's a good idea to inspect them every few months, especially if you notice any issues with stability.

Can I replace just the rack supports instead of the entire rack?

Yes, if only the supports are damaged, replacing them can be a cost-effective solution.

What if the new racks still don't fit properly?

Double-check the model number and ensure you have the correct parts. If the issue persists, consult the manufacturer.
