Regardless of what the remote access test says about it being available, I had to manually port forward to fix this same issue.

Seriously, can’t get those 15 minutes back.

Not what you’re asking, but have you tried sharpening your cartridge blades? I’ve been using the same store brand 3 blade cartridge for a few years now, just stropping by swiping it in reverse up my arm 10-20 times right before shaving in the shower. Shave is close, no razor burn. Considering you’re concerned about waste, zero waste in a few years seems worth mentioning.

Whenever you do get it clean, treat it with RainX or similar. We do that every few years and squeegee after each shower, our glass is spotless after 10 years. Our water is super hard too, saw the house next to ours which was built at the same time, disgustingly opaque with scale.

All the expensive coffee machines say not to use RO water. Apparently RO water is slightly acidic and can damage the copper heating elements over time. I’ve a RO system and love the taste (really lack of any flavor), but stopped using it on my coffee machines.
