Raypak 601588 Circuit board

Raypak RP2100 601588 is a digital pool/spa control circuit board (model 2.1/2.2) that manages heater, pump, and lighting functions via a 12‑V DC interface. Common failure modes include blown power supply capacitors, tripped or burnt relays, and degraded PCB traces from moisture ingress; the board often shows error codes such as “E01” (heater fault) or “P02” (pump off). First‑check diagnostics: verify 12‑V input voltage and continuity to the board’s Vcc pads, inspect for visible burn marks or swollen electrolytics on the power section, and review the diagnostic LED/error code display for specific fault codes.[oss-gpt-20b]
