Sediment wouldn't normally build up a pile so high as
to block entry/exit. But worth a try as diagnostic.
See if the heater inlet/outlet connections are
equipped with "heat traps". Shiney nipple,
maybe 3-4" long. Looks exactly like a
"dielectric" nipple but has a tiny ball check inside.

Maybe a dip tube collapse, but that seems far-fetched.
