I have a GRXB bunn 900 watt 10 cup coffee maker that leaks from the bottom when you add water. can you help me find the problem

probably a broken hose

There is a seal kit that is successful about 90-95 percent of the time in fixing the leaking issue. If you will call customer service at 800-352-2866 with your name and address, we will be able to send you a kit to resolve your issue.

If you will call Customer Service at 800-352-2866 with the model and date code we can further assist you.

It sounds like a seal/gasket is defective causing it to leak. Please locate the model and date code on the bottom of the brewer and contact customer service for troubleshooting and replacement options.

Adjust the grind of the coffee, it is too fine.

I will be happy to assist you with this issue if you would provide your model and date code which are located on the bottom of the unit.

there's probably a 'silicon rubber' hose that feeds hot water to the 'grounds basket'- it may be loose, or damaged. is it leaking water, or coffee?? we have a bunn 8-cup, which has a pre-heated water tank that brews a pot in about 3 min. energy waster, but when you need coffee, you need coffee!!! is your filter holder properly centered? is the carafe lid hole clean and un-obstructed?
if it's leaking water, and not too costly to replace- you may consider replacing it with a new one!
good luck!

Hi.
This needs surgery - so make sure it's unplugged, then remove the base & covers.
Look for leaks around seals and pipes.
80% of the time - it's a seal that is faulty. You can contact the manufacturer for a replacement - or - just use standard silicone sealant to apply a thin layer over the defective area of seal - then re-assemble.

Silicone is so effective thesedays - that engine sumps are "glued on" rather than using a solid gasket. I'ts cheap and effective for repairs like this also.
