DWR has deteriorated surprisingly fast?

I bought a Beta LT jacket back in September for urban use, hiking and skiong. It’s been used basically daily (for about 4 months) up until two weeks ago by me in urban Stockholm and the Swedish countryside. Now I’ve had goretex clothing before so I know that the coating goes away after a while and that you need to wash and respray it with DWR. But the beading never went away as fast as it has with the jacket. It’s soaking especially around the cuffs and the head. It rains a lot in Stockholm and it’s been with me pretty much everyday but I’m wondering if there’s something else that could affect it.

I work as a receptionist and I usually hang the jacket while at work inside a clothing room which is next door to a large dishwasher. Wondering if this could have had an effect on the deterioration of the beading.

Thanks in advance!
