Since soakaways are buried underground, identifying a blockage requires looking for surface-level "red flags":
There are several reasons why a gutter soakaway may become blocked. One of the most common causes is the accumulation of debris, such as leaves, twigs, and other organic matter, which can enter the soakaway through the gutter system. Over time, this debris can decompose and form a compacted layer that prevents water from penetrating the soil. Another cause of blockages is the infiltration of sediment and silt, which can enter the soakaway through surface runoff or groundwater flow. Additionally, roots from nearby trees or plants can grow into the soakaway and cause blockages. gutter soakaway blocked
Compacted soil or a failing system can cause the ground to sag or form visible dips. Another cause of blockages is the infiltration of

Hire a drain jetting machine (or a plumber). Jet water backward from the soakaway access point toward the downpipe.
If the soakaway pit contains significant sediment build-up:
