| # | Ref | Identification | Part / marking | Category | Confidence | Notes |
|---|---|---|---|---|---|---|
| 1 | AC/DC flyback converter (daughterboard) | sub-PCB: transformer, bulk e-caps, CM choke, X2 cap, Y caps, CN2 | Power | likely | Isolated low-voltage supply for the electronics. Output voltage(s) unknown (measure). MAINS POTENTIAL on the primary side. | |
| 2 | F1 | Fuse T2A/250V (SMPS input) | silkscreen 'F1 T2A/250V' | Power | confirmed | Protects the AC/DC module. If the module has no output, check this first, with the device unplugged. |
| 3 | Main fuse (cartridge in clips) | ceramic/glass cartridge fuse | Power | confirmed | Rating not legible. Probably sized for the 1200 W heater path. | |
| 4 | Heater relay (black, sealed) | PCB power relay | Power | likely | Switches the heater. Marking scratched. Could also be a safety cut-off relay paired with #5. | |
| 5 | Grey box component (2nd relay or film capacitor) | Power | guess | |||
| 6 | Yellow dipped component (MOV or Y-cap) | Power | guess | |||
| 7 | Mains input terminals (L/N) | 2 PCB spade/tab terminals | Connector | likely | ||
| 8 | C25 | Film capacitor (grey box) | box film capacitor (X2?) | Power | likely | |
| 9 | J23 J24 J25 J28 J30 | 5 wire terminals (2-pad each) | slot/tab terminals | Connector | likely | Heater element, pump motor, thermal cut-off and/or earth wiring. Assignment TBD. |
| 10 | J19 | 2-pin wire connector | JST-style | Connector | confirmed | Function TBD (temperature sensor? pump?). |
| 11 | J12 | 2/3-pin wire connector | JST-style | Connector | confirmed | Function TBD. |
| 12 | J15 | ~8-pin wire-to-board connector (white) | Connector | confirmed | Function TBD. Multi-pin, so probably sensors or motor. | |
| 13 | U10 | TSSOP IC, unidentified | TSSOP-16 class | Unidentified | guess | Next to the relay with a resistor array. Candidates: relay/zero-cross logic, power metering, or op-amp sensing. |
| 14 | U5 | small 6-lead IC | SOT-23-6 class | Unidentified | guess | |
| 15 | Q5 Q8 R26-R55 | Small-signal transistor/resistor cluster | Unidentified | guess | Possibly relay/pump drivers or sensor conditioning. | |
| 16 | PCB finger (sensor tail) | long narrow PCB extension with pads at the tip | Sensor | guess | Reaches down into the stainless tube. Probably carries the water-temperature sensor at the tip (see R57 on the bottom side). | |
| 17 | Silkscreen 'ANOVA_PRO_POWER_REV01' | board name + revision | Marking / label | confirmed |
