Kennewick control board problems, in order of frequency
Because the shop sits on W 20th Ave, Kennewick board calls get the full bench treatment: pack pulled, relays and sensor inputs read, and a repair at board level where a welded heater relay or a blown fuse is the only real fault.

City water off the Columbia River runs about 7 grains hard in Kennewick — moderate on paper, but a heater element still collects a visible scale coat within a season or two. We work the Columbia Drive waterfront, Yelm Hill, Southridge, Canyon Lakes and the rest of Kennewick (99336, 99337, 99338).
The usual control board complaints from Kennewick
Nothing at all after a storm
A surge through the feed; sometimes a fuse, sometimes the whole pack.
Heater relay welded on
Water climbing past the set point: the heater relay contacts have fused, a board-level repair on most packs.
Pump relay dead
One pump never starts though the topside calls it — the relay or its driver has failed.
How the visit runs
- One price after diagnosis, in writing, before work starts
- Common parts on the van — most jobs finish in one visit
- Anything ordered is usually next business day
- Full cycle test with the panel off before we leave
- A straight answer if replacement beats repair
Our work stops at the spa's own cabinet: everything inside it — pumps, heater, pack, jets, plumbing — is ours; the house panel, feed conduit and installations belong to an electrician or a dealer.
