Spa jet flow

I have a fairly new in ground pool/spa combo. Out of the blue, when I put it in spa mode, the jets produce water but no bubbles or good water rippling like normal. They act like the regular pool jets. When I turn on the blower, the bubbles blow although not as crazy as normal. I noticed on the Jandy filter gauge, when in pool mode the psi is at or below the “clean” level but when I put it in spa mode it goes up to near “dirty” level. What is causing this?

I have a fairly new in-ground pool spa
00:04.7 00:10.3
combo out of the blue when I put it in
00:07.0 00:13.1
spa mode the Jets produce water but no
00:10.3 00:13.7
bubbles or good water rippling like
00:13.1 00:16.1
normal
00:13.7 00:19.3
they act like regular pool jets when
00:16.1 00:21.2
they turn on the blower the blower will
00:19.3 00:24.4
blow bubbles although not as crazy as
00:21.2 00:28.2
normal I noticed on the Jandy filter
00:24.4 00:31.0
gauge when the pool went in pull mode
00:28.2 00:33.4
the PSI is at or below the clean level
00:31.0 00:38.3
but when I put it in spa mode it goes up
00:33.4 00:38.3
to near dirty level what is causing this
00:38.8 00:46.2
so the obvious answer is when you’re in
00:42.7 00:49.3
pool mode the pressure on the lines is
00:46.2 00:51.3
much less because probably there’s less
00:49.3 00:55.0
restriction in the line maybe how the
00:51.3 00:57.1
spa was built as soon as the pump kicks
00:55.0 00:59.5
out or goes into spa mode there’s back
00:57.1 01:02.2
pressure because however the spas
00:59.5 01:04.3
plumbed it’s putting pressure the pump
01:02.2 01:06.3
is having to work harder to push water
01:04.3 01:09.2
through those lines so it could simply
01:06.3 01:10.6
be how it was plumbed is always a
01:09.2 01:13.6
possibility that maybe there’s a
01:10.6 01:14.7
blockage in the spa line although that
01:13.6 01:16.3
doesn’t make a whole lot of sense
01:14.7 01:18.8
because there’s really no way of getting
01:16.3 01:21.0
anything in there to block that line on
01:18.8 01:22.7
the pressure side on the suction side
01:21.0 01:25.5
potentially but not on the pressure side
01:22.7 01:28.6
so likely the pressure goes up because
01:25.5 01:31.6
of the way that it’s plumbed it just has
01:28.6 01:31.6
that much more back pressure
