Lamona Dishwasher Problems
The Problem:
Owners of the Lamona HJA8630 dishwasher from Howdens have encountered an issue where all the programme lights on the appliance are illuminated, preventing it from starting. This problem has occurred intermittently in the past and, after some time, the machine would reset. However, some users now report that the reset isn’t working, rendering the dishwasher inoperative. Furthermore, the absence of a manual has left users unsure about troubleshooting.
Potential Solutions and Insights:
- PCB Replacement:
- One of the primary reasons behind the illuminated lights issue is a problem with the printed circuit board (PCB) located beneath the buttons. Over time, this PCB can corrode, leading to the malfunction.
- It’s worth noting that the Lamona HJA8630 dishwasher is structurally similar to the Beko DW600 model. Thus, parts and solutions applicable to the Beko model can often be used for the Lamona model. Fortunately, replacing the PCB for this model isn’t expensive, with costs being considerably lower than other brands, like Smeg.
- Module or Display Module?:
- The problem primarily relates to the module, not the display module. This distinction is crucial for those considering replacements or repairs.
- Capacitor Replacement:
- Before completely replacing the module, another potential solution is to focus on replacing the large grey capacitor on the board. In some instances, changing this capacitor has resolved the ‘all lights on’ issue.
- For those with a technical inclination, they can replace both electrolytic capacitors on the main board. This method has proven effective in resolving the display panel problem for many users. An added advantage of this approach is that it’s cost-effective and can extend the life of the existing board.
- Heater Relay Issues:
- In addition to the display problem, a malfunctioning PCB can lead to issues with the heater relay. Specifically, it might cause the relay to burn out, which in turn results in the heater not switching off while water is inside the dishwasher. If users notice unusual heating behavior alongside the display issue, they should consider checking the heater relay.
Conclusion:
The ‘all lights on’ problem with the Lamona HJA8630 dishwasher can be inconvenient, but several potential solutions ranging from capacitor replacements to a full PCB swap can address it. While professional assistance is always recommended for appliance repairs, some solutions can be DIY, especially for those with electronics experience. Lastly, sharing knowledge and experiences, as done by numerous users, is instrumental in finding effective and lasting solutions.
